Repairing epigenetic Defects can Slow down Aging

By Ray Schilling | Anti-aging medicine, green tea, regenerative medicine, Stress management

A new publication found that repairing epigenetic defects can slow down aging. This is a newer concept, which is gaining momentum in the longevity research world. David Sinclair is a professor of genetics at the Blavatnik Institute at Harvard Medical School. He is also co-director of the Paul F. Glenn Center for Biology of Aging Research.

Here is the summary of how epigenetic factors can slow down aging:

Double-stranded DNA breaks can erode the epigenetic landscape
Loss of epigenetic information accelerates the hallmarks of aging
Epigenetic reprogramming changes aging into more youthful appearance
Researchers can manipulate the epigenome, thus driving aging forward and backward

Professor Sinclair said that the conventional thinking about aging is no longer sustainable. The old theory was that genetic mutations undermine our DNA, creating a junkyard of damaged cellular tissue that leads to deterioration, disease and death. Instead, Dr. Sinclair said: “We believe it’s a loss of information – a loss in the cell’s ability to read its original DNA so it forgets how to function – in much the same way an old computer may develop corrupted software. I call it the information theory of aging.”

Here is what Dr. Sinclair and his team have established

DNA in the cells function like the body’s hardware. The epigenome is the software.
Proteins and chemicals make up the epigenes that sit “like freckles on each gene”. It is the epigenome that turns genes on and off. Pollution, environmental toxins, human behaviors such as smoking, eating an inflammatory diet or suffering a chronic lack of sleep will all trigger a change in the epigenetic information. Dr. Sinclair added: “And just like a computer, the cellular process becomes corrupted as more DNA is broken or damaged.”
“The cell panics, and proteins that normally would control the genes get distracted by having to go and repair the DNA,” he explained. “Then they don’t all find their way back to where they started, so over time it’s like a Ping-Pong match, where the balls end up all over the floor.”
“The astonishing finding is that there’s a backup copy of the software in the body that you can reset,” Sinclair said. “We’re showing why that software gets corrupted and how we can reboot the system by tapping into a reset switch that restores the cell’s ability to read the genome correctly again, as if it was young.”
Sinclair went on to say: “It doesn’t matter if the body is 50 or 75, healthy or affected by disease. Once that process has been triggered, the body will then remember how to regenerate and will be young again, even if you’re already old and have an illness. Now, what that software is, we don’t know yet. At this point, we just know that we can flip the switch.”

History of longevity research

Dr. Sinclair started his research into longevity as a graduate student by working with yeast cells. He studied the genes that controlled aging in yeast. After he identified the aging gene, he also could determine the same gene in mice. He developed ICE, short for “inducible changes to the epigenome”, basically temporary, fast-healing cuts. They mimic the aging process due to exposure to pollution and sunlight. Mice treated with the ICE method for one year looked like regular mice would look after two years. The Sinclair team of researchers were able to age tissues in the brain, eyes, muscle, skin and kidneys of mice using the ICE method.

Mice turning younger again

But what is more important, they also showed that these aged mice could turn younger again. Dr. Sinclair’s researchers took human adult skin cells, reprogrammed them to behave like embryonic or pluripotent stem cells and injected them into the older mice. To their surprise this triggered the test animals to become younger again. Dr. Sinclair said that fortunately they went back to an age between 50% and 75% of the normal life span. None of the animals developed cancer. The researchers injected the cocktail into damaged retinal ganglion cells at the back of the eyes of blind mice. Then they activated the rejuvenation process of the retinal ganglion cells by feeding the mice antibiotics. Surprisingly, the mice regained most of their eyesight. In a similar way the researchers could rejuvenate aged muscle cells, skin cells and kidney cells of mice.

Human longevity

We are not at the point yet where human research similar to mouse research is being done. But Dr. Sinclair is convinced that more human data will be on the way. He pointed out that telomere tests of leukocytes in blood tests of individuals with healthy lifestyles already show that they have a significantly lower biological age compared to their chronological age. His advice for longevity is this:

Focus on plants for food and eat less often
Get sufficient sleep
Exercise regularly and get short-winded for 10 minutes at least three times a week
Regular exercise will also help you to maintain your muscle mass
Don’t get upset about unimportant things. In other words, manage your stress
Have a good social support group

Other ways to reduce your biological age

I attended the 22nd Annual World Congress on Anti-Aging Medicine In Las Vegas (Dec. 10-14, 2014) that dealt with telomere length and how nutrition can positively influence what our genes express. This ultimately determines how long we live. Dr. Al Sears gave one of the talks at the conference. He pointed out that shortened telomeres are causing cells to behave like old cells. In the lab we can lengthen telomeres. Telomerase activated animals regrew their brains! In the human situation the goal is to find ways to preserve the length of our telomeres in all our key organs. Dr. Sears said a patient with short telomeres who starts telomerase stimulating supplements, develops longer telomeres in leukocytes within one month of commencing the supplementation.

The following supplements lengthen telomeres

Dr. Sears pointed out that the following supplements lengthen telomeres in humans.

Acetyl-L-carnitine and resveratrol are two substances that reliably elongate telomeres.
Vitamin C will significantly delay shortening of telomeres resulting in delayed aging.
In addition, researchers showed recently that vitamin C stimulates telomerase activity in certain stem cells.
The herbal Silymarin extract increases telomerase activity threefold.
N-acetyl cysteine is a building block for glutathione, a powerful antioxidant. In addition, it has been shown to turn on the human telomerase gene.
Other telomerase stimulators are green tea extract, ginkgo biloba, gamma tocotrienol (one of the components of the vitamin E group), vitamin D3 and folic acid.

The following link lists Dr. Sears’ recommended daily doses of these telomerase stimulating supplements.

Repairing epigenetic Defects can Slow down Aging

Conclusion

Epigenetic defects appear to be more important than genetic abnormalities. The problem is that epigenetic changes through pollution or sun exposure can switch off genetic switches. This makes us age much faster than healthy controls. In this review I described mouse experiments that Professor David Sinclair did. He is professor of genetics in the Blavatnik Institute at Harvard Medical School, Boston, MA. He demonstrated in mice that he could age them faster with the ICE method, short for “inducible changes to the epigenome”, basically temporary, fast-healing cuts. They mimic the aging process due to exposure to pollution and sunlight. He also showed that these aged mice could turn younger again.

Rejuvenation of older mice

Dr. Sinclair’s researchers took human adult skin cells that have been reprogrammed to behave like embryonic or pluripotent stem cells and injected them into the older mice. To their surprise this triggered them to become younger animals again. None of them developed cancer and they turned back to 50% to 75% of their original age. There is no application to humans yet, but Dr. Sinclair’s team is planning to address this issue next.

Stem Cell Therapy Is a New Way to Treat Osteoarthritis

By Ray Schilling | Arthritis, back pain, chronic pain, osteoarthritis, Pain, regenerative medicine, stem cells

Traditional treatment for osteoarthritis is not very successful, but stem cell therapy is a new way to treat osteoarthritis.

Traditional treatment of osteoarthritis

Osteoarthritis is a common degenerative type of arthritis. Wear and tear are diminishing the hyaline cartilage that coats joint bones. The lubrication of synovial fluid is diminishing as well. The end result is that the patient suffers pain from bone rubbing on bone in affected joints with swelling of the synovial membranes. The physician usually prescribes diclofenac topical solution for the affected joints and also gives anti-inflammatory drugs by mouth (diclofenac or ibuprofen). Unfortunately, the patient may develop side effects of the anti-inflammatory medication, such as kidney damage and gastritis. The end result after years of suffering is that the joints turn stiff and the joint pain becomes unbearable.

Joint replacement surgery

This is when the doctor refers the patient to an orthopedic surgeon, and an artificial hip or a knee joint replacement is the next suggestion. These surgical procedures are not without dangers. Postsurgically blood clots can develop and cause pulmonary emboli. Infection and sepsis can also develop. Often the surgery does not solve all of the problems and leaves the patient with a permanent limp.

Stem cell therapy to treat osteoarthritis

Regenerative medicine has developed an alternative to the conventional treatment of osteoarthritis. I described this new approach to osteoarthritis before here.

Stem cells are harvested from fatty tissue of the patient and injected into the affected joint. Stem cell stimulators like platelet rich plasma and low-dose laser therapy activate the stem cells that were lying dormant in the fatty tissue. These type of stem cells are mesenchymal in origin, so they go by the name of mesenchymal stem cells. When injected into a joint with osteoarthritis they can transform into any tissue that is needed to repair the damage of the joint. A defect of the hyaline cartilage is covered by stem cells transforming into cartilage cells and fixing the hyaline cartilage defect.

What stem cells do

Stem cells fix any meniscal degeneration in the knee joint by mending what is degenerated. They can form new tissue that over-bridged mini tears in the meniscus. If the synovial membranes that produce joint lubrication are damaged, the stem cells rejuvenate the old tissue and joint lubrication normalizes. The end result following stem cell treatment is that the osteoarthritic joint becomes regenerated with normal function. Stem cell treatment normalizes the osteoarthritic process in the joint, and down the road no joint replacements are necessary. This is a huge advantage in comparison to the conventional treatment of osteoarthritis.

My own experience with stem cell therapy for osteoarthritis of my left knee

I have experienced mild left knee arthritis for 5 years. It was not severe enough to treat with anti-inflammatory pills. I used higher amounts of fish oil capsules, which helped somewhat. I heard that Dr. Michael Weber from Lauenförde, Germany treats osteoarthritis with stem cell therapy.

He had treated my back successfully on several occasions in the past. I had previous stem cell treatment 4 years earlier as summarized here. Part of this was stem cell therapy for my left knee. During the Covid time I could not go to the gym for a period of time. Instead, I went for long walks on a nature trail that was bumpy and had many roots. This flared up my previous problem with my left knee. But in early June 2022 I made my way back to Dr. Weber’s clinic for more stem cell therapy.

The following summarizes how he treated my left knee with stem cells.

Liposuction to harvest stem cells for treatment

The doctor used a local anesthetic to freeze the skin and subcutaneous tissue on the right flank. Subsequently a solution of normal saline that contained adrenaline and bicarbonate was injected. This allowed Dr. Weber to withdraw fatty tissue easier 20 minutes after the normal saline injection. The generous portion of fatty tissue harvested was brought to a cell separator, which separated stem cells, fat cells and connective tissue. The stem cells were counted by a technician. They were found to be 100% viable and there was a total of 980 million stem cells.

Intravenous stem cells

Dr. Weber administered one portion of the total stem cell harvest intravenously. I was told that this ensured that stem cells would be delivered to tissues that needed renewal through stem cell therapy. There are several methods to stimulate stem cells. One of these methods is to give oxygen intravenously with a device with the name Oxyven (from Swiss Medica) . This procedure took 20 minutes. A second method to stimulate stem cells is with low-dose laser therapy. Dr. Weber used intravenous red, green, blue and yellow lasers, for 20 minutes each.

The laboratory kept the rest of the stem cells overnight at room temperature. Dr. Weber told me that it would have been a mistake to keep the stem cells in the refrigerator overnight as the cold temperature kills all of the stem cells!

Targeted stem cell therapy

The following day I received treatments with my stem cells harvested the day before. The doctor drew blood up first, which underwent centrifugation. The interface between the red blood cell portion and the plasma contains PRP (platelet rich plasma). Dr. Weber mixed PRP in with the stem cells. PRP is a powerful stimulator of stem cells.

Dr. Weber inserted a needle into my left knee and injected stem cells (and PRP) into the left knee. Following this he inserted a thin sterile fiberglass applicator. This served to introduce four laser lights into the knee, namely red, green, blue and yellow low-dose laser beams. Dr. Weber connected each for 20 minutes. He explained that the laser light activates the stem cells, similar to PRP and to oxygen (Oxyven, Swiss Media).

Lower cervical spine, upper thoracic spine and lower lumbar spine also treated

I get monthly chiropractic manipulations to my spine to stabilize it. My chiropractor told me that it would help to have stem cell therapy in the C4 to T4 area of the upper spine and in the L4 to S1 region in the lower spine. Dr. Weber concentrated his treatments on exactly these levels of my spine. He placed interstitial needles over the facet joints bilaterally in the lower cervical spine, upper thoracic spine and lower lumbar spine. Subsequently he injected the stem cell/PRP mix and followed this up with the four laser lights for 20 minutes each.

Follow up after the stem cell treatments

There was a lot of swelling in my left knee during the first two days after the stem cell treatment. I also experienced pain with walking. But on the third day the swelling disappeared completely. After 1 week the previous mild left knee pain improved significantly. After 1 month the left knee no longer ached with stairs or uneven ground. Presently I am still completely pain-free. My back pain also disappeared within 2 to 3 weeks.

Stem Cell Therapy Is a New Way to Treat Osteoarthritis

Conclusion

When it comes to the treatment for osteoarthritis, conventional medicine offers topical and oral anti-inflammatory medicine. Usually, the physician also recommends active exercises and heat applications by a physiotherapist. When anti-inflammatories no longer work and bone rubs on bone in a hip or knee joint, total hip or total knee replacement by an orthopedic surgeon is usually the next step. Unfortunately, these surgical procedures have a certain complication rate. They often do not lead to perfect end results with residual pain and possibly a limp

Stem cell therapy is usually not what a family practitioner recommends. But when the physician does stem cell therapy at an early stage, the success rate is good and as in my case you can always do another stem cell therapy to improve the knee or hip joint further. There are three procedures that help to stimulate stem cells: platelet rich plasma (PRP), intravenous oxygen (Oxyven, Swiss Media) and low-dose laser activation. In my case Dr. Weber applied all of these methods together with stem cell therapy. Improvement in my case was very rapid, and it was a delight to witness the result of stem cell therapy as a patient.

Clinical Applications of the Fasting Mimicking Diet

By Ray Schilling | Alzheimer’s disease, Anti-aging medicine, autoimmune disease, Cardiovascular disease, Diabetes, diet, fasting mimicking diet, food, Health, Hormones, Inflammation, lifestyle, mitochondria, Multiple sclerosis, Prevention, regenerative medicine, stem cells, telomeres, Weight loss

Dr. Kurt Hong, professor of clinical medicine spoke about clinical applications of the fasting mimicking diet in Las Vegas. This was at the 27th Annual World Congress on Anti-Aging Medicine on Dec. 14, 2019. Although he spoke on various forms of fasting, he concluded that the fasting mimicking diet had the best results and was most consumer-friendly.

How we age

Dr. Hong reviewed the processes of aging. We age, because our cells experience oxidative damage and our telomeres (the end caps of our chromosomes) get shorter in time. We also age, because there are genetic mutations in our cells’ DNA and our mitochondria are aging as well. The mitochondria are the small energy packages inside the cells that give us energy. When people age, they have lost mitochondria, there is less energy that the body makes out of food and we feel chronically tired.

Above the age of 65 we are also likely to develop diseases of various organs:

Heart disease: 31%
Cancer: 24%
Chronic lung disease (lower respiratory disease): 21%
Alzheimer’s disease: 13%
Diabetes: 11%

Women are generally healthier than men and their life expectation is 4 to 5 years longer than that of men.

Cellular and molecular aging

Longevity researchers have done mouse experiments and human clinical trials for decades. Dr. Hong asked the question: how much longer could humans live, if we could cure cancer, heart disease, stroke and diabetes? The answer is: 13 years. But if we transfer the animal data to humans it should be 30 years of longer life. Why is there such a discrepancy? The answer is that it is easy to force good lifestyles onto animals, but humans are resistant to changes. Humans have their habits; they like to continue to smoke and eat fast food instead of switching to a healthier Mediterranean diet. Humans also resist a regular exercise program. And they do not want to hear that they should replace missing hormones with bioidentical ones. The result is that we humans will prolong our lives only by less than 50% of what we could achieve.

The concept of intermittent fasting

Dr. Hong stated, that ten thousand years ago, people did not always have enough food to eat. They were forced to intermittently fast. That did not mean that they had long life expectancies, as there was no cure for any disease. But one fact was true: the body learnt to rejuvenate itself during periods of fasting. And these longevity genes are still present in our genes. But they will only help us when we actually fast for some periods of time.

Dr. Hong reviewed what kind of fasting methods are available.

Prolonged fasting and juice fasting are not among the options. With prolonged fasting electrolyte disturbances become an issue. Juice fasting does not remove enough calories and nutrients. This, however is needed to allow the body to stimulate the longevity genes.

How fasting diets work

Dr. Hong explained that there are essentially 5 fasting diets that are effective in regulating the key nutrient sensitive pathways of IGF-1, TOR and PKA. This increases cellular protection and maintenance. It also increases activation of stress resistance pathways and removes and replaces damaged and dysfunctional cells. Finally, a fasting diet also reduces inflammation, which is often the start of disease.

A review of the 5 fasting diets

Time-restricted eating (TRE)

With TRE the person fasts for 12 to 16 hours every day. The person restricts the daily food consumption to a 4- to 12-hour window. The disadvantage is that this fast is done every day. The period of fasting may not be long enough to change the metabolism, where the above-mentioned effects take place.

Alternate-day fasting

This is a 24-hour fast every other day with a 1:1 day eating-fasting cycle. This does not appear to be physiological and is disruptive with regard to social activities.

5:2 intermittent fasting

With this fast you fast for 2 days every week. With this 2:5 eating-fasting cycle the person fasts for 2 days every week; the other 5 days you eat as much as you desire.

Although this is effective, it can be quite disruptive to your lifestyle.

Periodic fasting

You fast for 48 to 72 hours every couple of months. This fast is socially more acceptable. It is not that often, just a couple of times in a year. The question remains whether it is effective in changing the metabolism to trigger the effects mentioned above.

Fasting-mimicking diet (FMD)

The original suggestion by Dr. Longo, the inventor of the FMD was that you should fast for 5 days once every month. Since then he has modified it and said that you can achieve similar metabolic changes, if you only fast for 3 days and do this a couple of times per year. I have done the FMD since December 2017 and I adhere to the original schedule of doing the FMD monthly for 5 days. This has provided me with more energy. It is easier to keep my body mass index in the 21.0 to 22.0 range. Dr. Hong explained that the FMD allows you to eat, but it tricks the body into acting like you are fasting. Because you are eating 500 to 600 calories per day, you are getting some fluid and nutrients, so the hunger pangs are tolerable.

More details about the FMD

Here is Dr. Hong’s summary about the FMD: “The stomach sees food, while the cells see fasting”. Dr. Hong said that the FMD is the most user-friendly method of fasting. It also has had the most scientific studies to validate that it is indeed working. Poorly functioning mitochondria and misfolded proteins are removed by a process of phagocytosis. The FMD reduces heart disease, cancer, and neurodegenerative disorders. Stem cell production also gets a boost. This promotes cell regeneration and reduces risk factors of premature aging.

Publication on the effectiveness of the FMD

A publication came out in 2017 reporting about the findings of a clinical trial regarding the FMD.

Researchers followed markers of aging, diabetes, cancer and cardiovascular disease in 100 volunteers. They underwent a FMD for 5 days on 3 consecutive months. The results were astounding. The body mass index, the fasting blood sugar level, triglycerides, total and LDL cholesterol and the CRP were all lower. CRP stands for C-reactive protein, which measures the degree of inflammation in the body. The blood pressure was also lower. Overall the 5-day FMD was a safe method with no side effects. The FMD reduced markers and risk factors of aging and age-related diseases. In doing so it prolongs life by reducing the likelihood of coming down with disease.

Who should abstain from fasting?

Dr. Hong mentioned that the FMD is not for everybody. Pregnant women should refrain from going on it, also type 1 and type 2 insulin dependent diabetics. Anybody who has a sign of an active infection (coughing, having a fever or diarrhea) should be excluded. Other exclusions are people who are underweight (BMI less than 18.5) or are malnourished (protein deficiency). Patients with heart failure and advanced kidney or liver disease should not take part in a fasting program.

Autoimmune diseases and FMD

The myelin sheath around the axon of nerve cells in the central nervous system are supported by oligodendrocytes. In multiple sclerosis (MS) patients T lymphocytes activate macrophages and B cells to produce autoantibodies. They destroy oligodendrocytes breaking down the insulating barrier of the myelin sheath. In MS patients the broken-down myelin sheath suppresses the electrical impulses transmitted through the nerve fibers. The FMD led to clinical improvements.

In a pilot study intermittent fasting changed the gut flora into a healthier flora.

This triggered the immune system in the gut to make less inflammatory T cells producing the IL-17 cytokines. There was also an increase in regulatory T helper cells.

Inflammatory bowel disease (IBM) can be improved with several courses of FMD. As the authors showed, intestinal inflammation improved with FMD. The intestinal gut flora improved with the FMD and it promoted intestinal regeneration.

Reversal of physical and functional decline

The fasting mimicking diet (FMD) has a variety of effects on the human body. Dr. Hong showed a slide where we could see that ketone bodies, cortisol and ghrelin levels are increased in the blood. At the same time glucose, insulin, leptin and IGF-1 levels are reduced. In addition, triglycerides and LDL levels are getting lower. Inflammatory markers including the C-reactive protein (CRP) are reduced as well.

Effects of the FMD on various organs in the body

A look at all of the organs shows that in the liver the ketone body production and insulin sensitivity are up. Glycogen production in the liver as well as the liver size are down.

The intestines produce ketone bodies. In the skeletal muscles the insulin sensitivity is increased, while the muscle structure and function are improved. In the brain the hunger feeling increases the release of neurotropic factors including the neuropeptide Y. Cognitive function and stress resistance increase with the FMD. The FMD reduces inflammation and oxidative stress in the brain. With respect to the cardiovascular system the heart rate drops down and blood pressure gets lower. The insulin production in the pancreas is reduced.

Fatty tissue

In fatty tissue lipolysis is up and also the production of adiponectin. This is a protein hormone involved in glucose and fatty acid metabolism. Insulin sensitivity with the FMD is also increased. On the other hand, the FMD reduces fat mass, leptin production and inflammation.

The FMD is the solution to preventing disease and prolonging your life

All of these effects lead to a reversal of physiologic and functional declines. Age-related metabolic diseases like type 2 diabetes are postponed or eliminated. The FMD prevents neuro-cognitive decline like Alzheimer’s disease. In addition, the risk of developing cancer is getting lower. In summary, the FMD improves the health-span, quality of life and can prepare you for a long life.

Clinical Applications of the Fasting Mimicking Diet

Conclusion

Dr. Kurt Hong is a professor of clinical medicine at UCLA. He gave a talk at the 27th Annual World Congress on Anti-Aging Medicine in Las Vegas on Dec. 14, 2019. He discussed what we could do to help patients with various autoimmune diseases like multiple sclerosis, rheumatoid arthritis and inflammatory bowel disease. It turns out that the fasting mimicking diet (FMD) is the best solution to reduce inflammation and modify the autoimmune response from aggressive T lymphocytes. With the FMD you consume only 500 to 600 calories per day for 5 days every month. The rest of the days of the month you eat a healthy Mediterranean-type diet.

Fasting mimicking diet, the best way to treat autoimmune diseases

Dr. Hong explained in detail what cellular mechanisms are at work to achieve the modification of the immune system in autoimmune diseases. The FMD is also the solution to slow down aging in healthy people. Dr. Hong discussed clinical applications of the fasting mimicking diet fort autoimmune diseases. It is easier to prevent disease than it is to cure an illness. The FMD is an easier way, because you don’t fast completely, you only reduce your food intake to the bare minimum, but your body “thinks” that you are fasting.

Ultimately, this approach does take some effort, and it does take time to familiarize yourself with it. If patients do it for the first time, they will experience some hunger, the first and second day tend to be a hurdle! Once you make it part of a health routine on a regular basis, it is a lot easier.

Orthopedics Without A Knife

By Ray Schilling | Arthritis, Orthopedics, Pain, regenerative medicine, scar tissue, stem cells, wound healing

Dr. Fields gave a talk in Las Vegas about orthopedics without a knife. His talk took place at the 23^rd Annual World Congress on Anti-Aging Medicine on Dec. 12, 2015 in Las Vegas. Dr. Fields gave a talk entitled “Regenerative orthopedics – non-surgical repair with stem cells/PRP/prolotherapy”. In essence the talk was about alternative treatments to surgeries in orthopedic medicine.

Dr. Peter Fields, MD, DC is a board certified medical physician and chiropractor. He is also the director of the Pacific Prolotherapy & Medical Wellness Center in Santa Monica, CA.

Introduction

Joints, muscles, tendons, ligaments and joint capsules control the movements in joints. Due to injuries and wear and tear these body parts can have a lack of function, which will lead to pain and disorders. The result can be weak, torn or damaged ligaments and tendons, arthritic changes, excessive joint motion, increased pressure, and a decrease in range of motion.

This is the common treatment cycle in medicine

Joint pain prompts you to see the doctor. You are told it is arthritis, and you get non-steroidal anti-inflammatories (NSAID’s). You come back with more pain, and you’ll get a stronger NSAID prescription. Eventually a cortisone injection is given, which helps for a few months, but then the pain reoccurs. The doctor arranges for an MRI scan. A referral to an orthopedic surgeon is likely to be the next step, and an arthroscopy (pinhole surgery) is arranged. In that case, if this does not resolve the pain, surgery like a knee replacement or hip replacement is suggested.

Common sayings when traditional medicine has nothing to offer

You may have heard some of these common sayings before. “Nothing more we can do about it!” -“I suggest you learn to live with it”- “You should never play that sport again!”- “Take these pain medications” and “The only alternative is surgery!”

The problem is, that none of these pieces of advice are really helpful. This type of approach does not treat the cause; it is directed against symptoms.

How to treat the cause?

Prolotherapy

Prolotherapy is a natural, non-surgical method to assist the body to heal torn soft tissues. It works in cases like torn ligaments, damaged tendons, cartilage, menisci or a torn labrum in the shoulder. Hyperosmolar dextrose solution is injected into the injured area. This stimulates the body’s healing forces and the body repairs what is damaged. More information is found here. In essence, prolotherapy fixes the cause, not just the effect; it heals, and it is permanent. Prolotherapy strengthens tissues, relieves pain and increases the range of motion in joints. There is 80 to 85% full pain relief and more than 80% improvement in range of motion. Prolotherapy promotes the healing of torn or damaged ligaments and tendons.

Conditions suitable for treatment with prolotherapy

Suitable conditions for treatment with prolotherapy are sports injuries, muscle tears, arthritis, tendinitis, bursitis, sciatica, TMJ problems, and fibromyalgia. Common areas treated with prolotherapy are the hip, knee, shoulder, ankle, neck, lower back and elbow. Dr. Fields showed MRI scans before and after prolotherapy treatments of ligament injuries within the knee and of shoulder ligament tears before and after treatment. Normally the physician expected these injuries to require surgery. But all that was done was one or two injections (prolotherapy treatments) with reactivation of the affected joint. There were astonishing results shown with MRI’s before and after herniated disc injuries and how they healed in a relatively short time following prolotherapy.

PRP prolotherapy

Platelet rich plasma (PRP) is a tool from regenerative medicine to amplify the healing response in connection with stem cell therapies . The lab technician takes blood from the patient and subsequently spins it down in a centrifuge. The platelet rich fraction (PRP) contains all of the growth factors, which have the healing power of the blood. The physicians combines this with prolotherapy to make healing even more successful. This is particularly useful for labral tears in shoulders, meniscus tears in knees and other localized injuries.

Stem cell prolotherapy

Stem cell therapy has been the gold standard for repairing more serious problems. Dr. Fields combines stem cell therapy with prolotherapy to treat more serious injuries like end stage arthritis. This is the case when bone rubs on bone, where conventional orthopedic medicine would offer a joint replacement in the hip or knee. Stem cell prolotherapy can repair any joint that has cartilage damage. A severe meniscus tear in a knee or a severe labrum tear in a shoulder would also be situations where stem cell prolotherapy is superior to surgery or to just using prolotherapy alone.

Here is a description of the procedure

Before the patient’s procedure the physician first harvests bone marrow stem cells by way of a pelvic bone aspirate; secondly the physician obtains mesenchymal stem cells from fatty tissue by aspiration of abdominal fat. A cell separator provides the stem cell fractions. The physician combines both types of stem cells, the bone marrow stem cells and the mesenchymal stem cells from fat as each one has its own strengths. These two stem cell types are more effective in combination to repair whatever tissue needs repair. Thirdly, the lab technician will draw blood from the patient to obtain PRP, which contains the growth factors needed to activate the stem cells to do their job of healing. The last step is that the physician now combines hyperosmolar dextrose (the prolotherapy part) with the stem cell preparation and mixed in PRP and injects this mixture into the injured area.

Conditions that respond to stem cell prolotherapy

This procedure has superior healing power. Before and after MRI scans of all of the major body regions showed impressive results. Several video recorded testimonials complemented the MRI scans. It is surprising how quickly and completely fairly severe injuries can heal using stem cell prolotherapy. One particularly nasty condition is osteonecrosis of the hip, which can occur as a side effect of chronic cortisone treatment for arthritis, asthma or chronic obstructive lung disease. One or two stem cell prolotherapy treatments will heal this condition because the stem cells build up brand new bone and get rid of the old necrotic bone from the osteonecrosis. Conventional medicine has no answer for this condition. Regenerative orthopedics is successful by using stem cell prolotherapy.

What are the advantages of regenerative orthopedics?

Regenerative orthopedics reduces pain very quickly and it improves function rapidly. Healing occurs naturally, and it strengthens the tissues involved. Particularly complicated lower back pains or lower neck pains (due to degenerative disc disease, facet joint osteoarthritis, spondylolisthesis and significant foraminal stenosis) respond really well to stem cell prolotherapy, getting rid of chronic pain. The speaker showed before and after MRI scans. He also shared testimonials from patients about the various procedures.

End result following stem cell prolotherapy versus conventional surgery

This is quite in contrast to what conventional orthopedics has to offer: discectomy with fusion surgery, where the patient often has scar pain later. With a laminectomy to treat a foraminal stenosis the patient may have limited improvement of the chronic back pain for a couple of months, only to experience new back pain from a subsequent spinal stenosis as a late complication from the prior surgery. The end result with conventional orthopedics is disability, pain and suffering; the end result with regenerative orthopedics is a patient that is well, active, pain free and thankful.

Orthopedics Without A Knife

Conclusion

There is a form of orthopedics without a knife: regenerative orthopedics. The tools are prolotherapy for minor musculoskeletal problems. Some very conservatively minded physicians still scoff at this, but wrongly so. PRP prolotherapy is suitable for more severe injuries that require more healing power. Stem cell prolotherapy is what the physician uses for the severe cases. All of the healing power (minus the knife) is put to use. Two types of stem cells initiate healing where there is a need for it. The stem cells transform into the cell types that do the repair.

Research has shown in the past that the mesenchymal stem cells alone will not heal cartilage of joints very well, but in combination with bone marrow derived stem cells this heals quite well and efficiently. Healing osteonecrosis and complicated lower neck and lower back problems borders to miraculous healing. Regenerative orthopedics is definitely something to remember should you get into trouble down the road. There are alternatives to the knife!

Life Extended By Several Decades

Have you ever thought about the possibility to prolong your “Freshness Date”? At the 23^rd Annual World Congress on Anti-Aging Medicine on Dec. 13, 2015 in Las Vegas the endocrinologist, Dr. Thierry Hertoghe from Belgium gave a talk about “How to extend the human lifespan by 40 years”. Dr. Hertoghe explained that it is possible to extend life by paying attention to the factors that prolong life and combining them as an anti-aging type lifestyle. He made a distinction between

normal aging: up to age 82
healthy aging: up to age 100
anti-aging medicine: up to age 122
reversing aging medicine: much more than 122, perhaps to age 150 or more.

Normal aging (up to age 82)

Life expectancy is on average about 82 years. From the age of 50 to 60 onwards you may encounter problems with increased cholesterol, high blood pressure leading to heart attacks and strokes. Coronary artery by-pass surgery may extend an individual’s life by 10 to 15 years. But hardening of the arteries in the general circulation will eventually cut down the blood supply to vital organs leading to premature death that could have been avoided.

Around the mid 60’s to mid 70’s 12.4% of African Americans or 2.9% Caucasians get Alzheimer’s disease. These figures worsen rapidly with further aging: in their mid 70’s to mid 80’s 32.5 % of African Americans and 9.8% of Caucasians suffer from Alzheimer’s disease. At the age of 85+ years 54% of African Americans and 27% of Caucasians have Alzheimer’s disease. With normal aging Alzheimer’s has already increased, and this trend likely is continuing.

Loss of memory, depression and musculoskeletal pain

Memory loss also leads to a shortened survival curve; people with memory loss live two years less on average than compared to a group with no memory loss.

Add to this loss of life because of depression, common in older age. Compared to a non-depressed group over 2 years of older people the depressed group lived 30% shorter.

Musculoskeletal pain in younger age (18-44) was 38%; the next demographic group aged 45-64 reported 61% of musculoskeletal pains; seniors between 65 and 74 had 68% of musculoskeletal pain, and in the demographic group of 75 and up 71% of persons suffered of musculoskeletal pain. As we will learn later there may be hormone deficiencies behind these neck and back pains. If the patient does not seek treatment, this can lead to falls, fractured hips and premature loss of life. Those who survive accidents often become wheel chair bound and end up in nursing homes.

Patients with rheumatoid arthritis and patients with other disabilities have a lower life expectancy

One specific subgroup of patients with musculoskeletal pain are rheumatoid arthritis sufferers. After 10 years of having rheumatoid arthritis patients will have a survival of only about 50%. With involvement of more than 30 joints (more severe form of the disease) only about 40% will survive. In other words, rheumatoid arthritis is an important factor for lowering people’s life expectancy.

At an age of 65 to 74 men have 23% of disabilities, while woman have 27.5% disabilities. This increases between the ages of 75 or older to 40% for men and 44.5% for women. At the age of 65 disabled men have a 3.5% higher death rate than the average population; disabled women’s death rate is 2.5% higher than the normal population. In other words, disability kills.

Obesity, and heart disease

Urinary urgency and incontinence leads to a 3.13-fold higher mortality rate than a control group of men who do not have these symptoms.

65% of men and 85% of women above the age of 50 have abdominal obesity. This is not just a harmless condition. There is an association between increased triglyceride levels and increased mortality due to cardiovascular disease and diabetes.

By the age of 65-74 heart disease has a frequency of 32% in men and 23% in women. At the age of 75 years and older this jumps to 44% in men and 32% in women. Once the doctor diagnoses heart disease, it causes a lot of premature deaths: an average person with heart disease lives 10 years shorter than those who do not have heart disease!

Healthy aging (up to age 100)

Improving lifestyle factors increases life expectancy

If we look at normal aging, we realize that all these diseases and disabilities we discussed are eventually killing us. In order to live longer we have to take steps that are known to interfere with some of these factors. For instance, quitting smoking will prevent heart disease, several cancers and chronic obstructive lung disease (emphysema). Positive thinking, social support and transcendental meditation will increase survival by preventing mental illness and depression, which in turn will prevent suicides. A healthy diet such as the Mediterranean diet or the Pegan diet will avoid cardiovascular disease and cut down cancer rates.

Live longer with better diet

One dietary change is called the “polymeal”. It consists of fish, fruit, vegetables, garlic, almonds, a moderate amount of wine and dark chocolate. Compared to the Standard American diet this type of diet would add 9 years for men and 8.1 years for women regarding their life expectancy. For instance, prostate cancer showed a 7-fold increase in a group of men who ate a lot of pickled vegetables, fermented soy products, salted fish and preserved meats, when compared to a control group who did not include these foods. In a group of women who had their meat well done and ate three servings of beef per week, breast cancer risk was 4.62-fold higher compared to women who ate meat done rare or medium rare. Overall cancer and cardiovascular mortality dropped by 35% in a study where 5 or more servings of fruit and vegetables were eaten per day.

Regular exercise and supplements of vitamin C and omega-3

A regular exercise program will strengthen the heart and lungs, keep your weight stable, reduce heart attacks and strokes and reduce the probability to develop cancer. A group of men between 61 and 81 were observed over 12 years and divided into those who did not exercise versus those who walked more than 2 miles per day. The exercising men had 19% less mortality compared to the sessile men. Vitamin C from fruit and vegetables or from taking supplements reduces global mortality from all causes by 46% compared to controls that did not. Similarly taking omega-3 fatty acid supplements (fish oil) daily reduced all cause mortality by 20%.

Dr. Hertoghe calls this “healthy aging” and this would allow you to be able to reach an age of about 100 years.

Anti-aging medicine (up to age 122)

Low thyroid hormones

Dr. Hertoghe told the audience that further attention to anti-aging factors could reduce mortality even further. He found over the years that paying attention to correcting hormonal weaknesses would have profound effects on how old a person becomes. Thyroid hormone replacement has been one of the steps that has helped people to feel more energetic, have less muscle pain, less falls, less fractures and complications. It also translates into longer lives.

One slide showed that a low free T3 level (low thyroid) was associated with a 3.6-fold higher death rate. A low free T3 level is an accurate predictor of cumulative death rate in cardiac patients.

T3 is also important for the maintenance of the immune system, which shows in patients with tuberculosis: the one-year mortality rate from TB in thyroid deficient patients was 75%, while patients with a normal thyroid had a mortality from TB of only 7%.

Replacement of missing sex hormones

Secondly, replacing missing sex hormones can add more life because cardiovascular disease is postponed (less heart attacks, less strokes), there is less cancer and better cancer survival, if a person comes down with cancer. Many statistics were quoted.

One interesting slide showed the longitudinal survival follow-up of congenital dwarfs in comparison with their normal brothers or sisters. Untreated male dwarfs turned only 56 years on average, while their unaffected normal brothers turned 75 years on average (19 years longer). With female dwarfs the difference is even more striking: untreated females dwarfs turned 46 years on average, while their normal sisters turned 80 years on average (a difference of 34 years).

Bioidentical hormone treatment prolongs life, lowers heart attack rates and lowers cancer rates

Another publication showed that the heart attack risk was 3.8-fold higher in a group of patients with hypopituitarism (under function of the pituitary gland), but the treatment group (treated with GH) had a normal rate of heart attacks.

11606 men aged 40 to 79 years were followed for between 6 and 10 years. The group who had the top 25% range of testosterone had a 19% lower mortality rates from heart attacks or cancer.

Older women, particularly aged 100 in Okinawa had 2.3-fold higher testosterone levels than women in the US at age 70. On the other hand 70-year old Okinawan women had 2.7-fold higher estrogen levels than US women.

Bioidentical hormone replacement therapy (BHRT) prior to developing breast cancer showed a 27% longer survival among 984 breast cancer patients in Sweden compared to those without prior hormone treatment.

Lower mortality rates for bioidentical hormone replacement therapy of breast cancer patients

In another group of breast cancer patients (2755 patients) aged 35 to 74 who were treated with bioidentical hormone replacement therapy (BHRT) after their breast cancer diagnosis, 50% had a lower recurrence rate (compared to no-BHRT treatment) and there was a reduction of 66% of mortality from breast cancer compared to controls without BHRT treatment. Another study showed that breast cancer patients would have a mortality rate of 33.3% without hormone treatment. After non-estrogen hormone treatment the mortality rate dropped to 12.5% and to 6% after estrogen/progesterone use. This shows the healing results of the various natural hormones.

Treating the cause rather than the symptoms

A group of 280 men and women around the age of 50 were treated with anti-aging hormone replacement for 2 or more years. In the beginning there were 34% of women and 15% of men with coronary artery disease. There were also 36.4% of women and 34.1% of men with high blood pressure. After replacing all of the missing hormones with bioidentical hormones for more than 2 years, coronary artery disease had dropped to 1.6% of the women and 1.08% of the men; high blood pressure had dropped to 2% of the women and 3% of the men. No drugs, just hormones! Of course, initially the doctors prescribed drugs to stabilize their condition, but they could gradually drop them safely. The reason was that the doctors treated the underlying hormone deficiency. The doctors were treating the cause of the cardiovascular disease rather than only the symptoms.

Low mortality of women on bioidentical hormone replacement

Dr. Hertoghe presented data of 6.38-year follow-up of 286 consecutive patients using anti-aging medicine (replacement of missing hormones with bioidentical hormones). These patients had an overall cancer rate of 2.1%, which compared very favorably to the 3.2% cancer rate among US women. The overall cancer rate was 3.1% in French women and 3.1% in Belgium women on no hormones. This is the type of information that is needed following the Women’s Health Initiative (WHI) that scared women into the false belief that hormones would be “poisonous”.

Synthetic hormone do not fit the hormone receptor

In the WHI synthetic hormones caused cancer and heart attacks; the reason for this was that synthetic hormones are not the identical shape as the natural hormones. But hormones and hormone receptors have to fit like a key into a lock; otherwise they are not effective or even block the natural life prolonging action of the natural hormone. This is why in the WHI study the outcomes were poor. Using bioidentical hormones the doctor can prevent heart attacks and strokes and they are also cancer-protective.

Reversing aging medicine (much more than 122, perhaps to age 150 or more)

General medicine has the goal to make patients as healthy as possible. With reversing aging medicine the goal is to make patients as young as possible. They are at their healthiest and feel younger again.

With anti-aging medicine using a healthy diet, exercise and bioidentical hormone replacement therapy the patients can add 15 years of good life. Add to these organ transplants, if necessary, telomerase activators and stem cell therapy. This can add another 25 years of life expectancy to a total of 40 years.

Growth hormone deficiency

Growth hormone deficiency is the one factor that has been underestimated. The discussion of dwarfs in comparison to their healthy brothers and sisters showed us the following. Growth hormone production can add between 19 and 34 years (average 26.5 years) of life. Dr. Hertoghe has done blood tests (IGF-1) and lately also 24-hour urine metabolite tests of growth hormone on aging patients and found that many are deficient with regard to GH production. These were patients where Dr. Hertoghe already replaced their thyroid hormones, if abnormal and replaced their sex hormones when they were low. But they lost hair, developed old looking faces with wrinkles. In addition, a loss of subcutaneous fatty tissue is giving the face a hollow appearance. They also had muscle and joint pains and thin skin, particularly over the back of their hands.

Replacement of growth hormone

He replaced their missing GH using daily GH self-injection with a tiny needle (similar to diabetes injections). Within 1.5 to 3 years the wrinkles disappeared, the faces started to look younger and patients did feel younger. Their muscle and joint pains had disappeared and their hair grew back. The dosage range is between 0.1mg and 0.3mg, a tiny amount of GH daily. This is not inexpensive, but some health care plans pay for this, as a lack of GH is a true hormone deficiency.

About organ transplants

Often it is a single limiting organ that determines when we die, typically the heart, lungs, brain, liver, kidneys, small bowel, pancreas or bone marrow. Organ transplants can add years of life, but it can be cumbersome to find a suitable donor. One study showed that only 40% to 60% of organ transplants are surviving 8 years after the surgery.

Stem cell therapies are other ways to prolong life. More research will perfect this, but essentially stem cells can provide 220 different cell types for in-vitro organ culture. This can probably be of use in the future to replace malfunctioning organs.

Life Extended By Several Decades

Conclusion

The dream of staying younger for longer can be a reality today. You just need to be willing to discipline yourself and watch what you are eating (Mediterranean type diet). Also, exercise regularly and have a positive psychological attitude. If the outdoor air is poor where you live, you may want to consider moving. Move to a place with good air quality. Sleep well for 7 ½ hours every night and retire not later than 10 to 11PM. You need to be asleep between midnight and 3AM as the growth hormone peak occurs at that time.

Take supplements

Take supplements that contain longevity micronutrients (magnesium, vitamins A, C, D, E, B6, B12, Co-Q-10, selenium, zinc, iron in premenopausal women etc.). Replace all missing hormones with bioidentical ones, like thyroid hormones (T3 and T4), sex hormones, DHEA and GH. Stem cell therapy and telomerase activators for cell rejuvenation will also have more of a place in the future.

Even, if you do only part of this reversing aging program you will slow down aging.

Tissue Repair With Extra Cellular Matrix

By Ray Schilling | extra cellular matrix, regenerative medicine, scar tissue, wound healing

Are you ready to learn about futuristic medicine consisting of tissue repair with extra cellular matrix? On September 5, 2015 I watched an interesting documentary on Discovery Channel while working out on the treadmill in the gym. This gave me the idea that this would be good material for a blog. After a little research on the Internet I found the full extra cellular matrix story, which you can read about below.

An amputated finger grows back

Lee Spievak, a man who loves flying model aircraft had an injury to his his right middle finger. A rotating model airplane propeller chopped off the end of his right middle finger. His surgeon felt that there was nothing much that could be done. But his brother who works in regenerative medicine knew about a powder made from pig’s bladder tissue, which Dr Stephen Badylak from the University of Pittsburgh, had pioneered. His brother sent a sample of powder (extra cellular matrix, ECM) to Lee Spievak who sprinkled some on the open wound (the stump).

New tissue forming with extra cellular matrix powder

Within two applications he saw that new tissue was forming. In a matter of 4 weeks it sealed up, the wound and a new finger grew to the same length as before. In the course of 4 months his nail, skin, his feeling and even his fingerprint were back to normal.

This story happened in Cincinnati in 2005. In this news story it is explained why the ECM powder worked so well: it prevented the wound from closing and it stimulated the body to heal.

A large thigh muscle defect grows back

Marine Sergeant Ron Strang was severely wounded by a roadside bomb in Afghanistan where a large part of his left quadriceps muscle (left thigh) was ripped off. After several surgeries the surgeons decided that Ron was a good candidate for part of a trial that is ongoing involving about 80 Veterans with similar injuries. Dr. Steven Badylak from the University of Pittsburgh suggested with the next surgery to put extra cellular matrix from pig bladder into the remaining quadriceps muscle to see whether it would regrow part of it.

Surgery with addition of extra cellular matrix from pig’s bladder

The surgery followed by physical exercise was so successful that Sergeant Strang is now able to run and do all the activities he wants. There is still a scar, but in comparison to the initial injury where a big chunk of muscle was missing, the remaining scar was insignificant.

Dr. Badylak explains in the video of the link that the insertion of the sheet of extracellular matrix immediately recruits the patient’s own stem cells, which makes new muscle cells, new nerve tissue, new skin, whatever the body needs to heal what’s missing in the injured area.

Dog gut growing into a dog aorta

Dr. Badylak from the University of Pittsburgh had a veterinary medicine degree before he studied medicine and became a surgeon. From the beginning his interest was in regenerative medicine.

After he saw the success with Lee Spievak’s finger regeneration, he thought that there must be a way to regenerate other tissues. He started doing experiments on dogs where he removed part the arch of the aorta and replaced it with a piece of gut from the same dog to see whether the dog would survive and whether the gut would be strong enough to withstand the pressure from the outflowing blood in the aorta. He figured that the tubular structure of the gut would be a better template than the synthetic aorta pieces that are still in use by thoracic surgeons. To his surprise the first dog (his own dog named Rocky) survived and did well.

Dog experiments to understand how extra cellular matrix works

He accumulated data on a total of 15 dogs. All of them survived and did well. He could not understand what had happened, so he reexamined one of these dogs where he got histological samples and analyzed them under the microscope to see what was going on. What he expected was the typical findings of the gut transplant, but instead he found a new aorta with all of the histological findings of aortic tissue. There was a transformation of a piece of gut into aortic tissue!

Next Dr. Badylak repeated the surgical procedure, but this time he inserted a piece of gut from a cat, removed the lining of it (the mucosa) and the muscle layer, (the muscularis),. The remainder was only the extra cellular matrix, a thin tubular structure of ECM.

Aorta scaffolding made of extra cellular matrix survives in dogs

When he was done, he was wondering whether the body would reject the catgut ECM. After all, it came from another species. Normally with whole organ transplants one can expect rejection of the foreign tissue. None of that happened. The experiment went flawlessly: the transplant survived like all the others and again the ECM had turned into dog aorta. It was possible to integrate the extra cellular matrix into the aorta without any scar formation! None of this fitted any conventional medicine model; it was the blueprint for the regenerative medicine model.

Dr. Badylak recognized that this was a huge step forward, and he would need easy access to ECM material. He got it from the pig slaughterhouses dotting the Indiana countryside surrounding Purdue. There would never be a shortage of tissue for preparing the scaffolding of the ECM for various applications.

Repair of tissue defects with extra cellular matrix in various body regions successful

By now the surgeon had proven that the gut or ECM transplant was switching off an inflammatory reaction, which suppressed scar formation, and simultaneously promoted regeneration. But the missing puzzle still was how the body generated the aortic tissue.

Dr. Badylak tested whether the procedure would work for large veins, smaller arteries and Achilles tendons. He did this all in dogs and using pig’s ECM. The answer was it worked all beautifully with no scarring and perfect healing results. Control dogs did not get the ECM, but were only operated on and then repaired conventionally in their Achilles tendons. They developed a limp from scar tissue. This is what often happens in humans as well with conventional surgery. But none of the dogs that had 3 cm cuts and then received a treatment with pig’s ECM developed a limp or scarring. They healed perfectly.

Large company supports Dr. Badylak’s work

In 1992 DePuy licensed Badylak’s ECM-derived “biologic scaffolds” for all orthopedic applications. DePuy is a big company that makes supplies for hip and knee replacements and much more. This was an ideal support for Dr. Badylak’s work.

In 1999 the FDA approved pig’s bladder ECM for human applications. This included the use of pig’s ECM for shoulder rotator cuff tears in patients. The FDA also approved it for abdominal hernias and for esophageal reflux damage. In addition the FDA approved it to induce the regrowth of the outer lining of the brain following brain surgery.

He could now continue his research and find out what the missing puzzle was. How did the body use the pig’s ECM and repair tissues?

Stem cell recruitment by ECM

Dr. Badylak was visiting a colleague of his in Los Angeles, Dr. John Itamur who had previously repaired a rotator cuff tear on a patient 8 weeks earlier using porcine ECM. The same patient had an unrelated shoulder injury. This required surgery just adjacent to the previously repaired rotator cuff. The surgeon decided to take a small biopsy to see how the healing tissue looked. This was when Dr. Badylak came for a visit. The microscope showed a surprise: the scaffolding had disappeared as expected. But there were a lot of new cells there. They did not look like inflammatory cells, muscle cells or nerve cells; they were stem cells. Dr. Badylak read several papers that told him that ECM breaks down into so-called crypteins. These peptides have powerful stem cell recruiting properties.

Experiment show how extra cellular matrix recruits stem cells

In 2003 he started groundbreaking experiments in mice that proved this theory to be correct. He X-rayed a group of mice to kill all of their bone marrow stem cells. Then he injected stem cells tagged with a fluorescent marker. They repopulated the bone marrow with these tagged stem cells from the same strain of mice. Now he removed a piece from the Achilles tendon and repaired the defect with pig ECM. Stem cells tagged with a fluorescent marker were flooding the Achilles tendon repair area. Even months after the Achilles tendon repair with ECM the new Achilles tendon was still filled with some of these tagged cells showing that some of them had matured into regenerated tissue.

Video showing would healing with extra cellular matrix and the final outcome of dog Rocky

Here is a link that contains a video about Sergeant Strang and his severe leg injury (repair of a rectus muscle tear). You may wonder how Rocky, the initial dog did who had an aortic segment replaced by a piece of gut. Rocky lived for another 8 years and was healthy until the very end.

Tissue Repair With Extra Cellular Matrix

Conclusion

You saw how the observation of a healing finger turned into experiments on dogs. Aortic defects and Achilles tendon defects healed without scarring. You learnt how pig’s or cat’s ECM were in use as scaffolds and that the body absorbed this. They recruit stem cells from the host’s body that subsequently do the healing. The exciting news about ECM is that it promotes healing, recruits stem cells, but also suppresses inflammation and scar formation.

We already hear that ECM is used in hernia repairs, rotator cuff repairs for shoulder injuries, and also in hair transplants, where Acell material is mixed in to improve the transplant success.

It is being used in lower esophagus surgery in cancer cases and with reflux esophagitis.

What will be the next application for ECM? We do not know everything, but it is a promising step into the future of regenerative medicine!
