Study Shows Bone Marrow Stem Cells Help Tennis Elbow

Tennis Elbow

A study published in the Jul-Dec 2014 edition of the Journal of Natural Science, Biology and Medicine entitled Bone marrow injection: A novel treatment for tennis elbow concludes that a single injection of bone marrow aspirate concentrate (BMAC) into the elbow lead to significant improvement of patients suffering from tennis elbow.

The study followed 30 patients for 12 weeks and concluded that treatment of tennis elbow patients with single injection of BMA showed a significant improvement in short to medium term follow-up.

Perhaps more importantly, it concluded that, “In future, such growth factors and/or stem cells based injection therapy can be developed as an alternative conservative treatment for patients of tennis elbow, especially who have failed non-operative treatment before surgical intervention is taken.”

Fast forward to the present where at RMI, we are augmenting BMAC with *AlphaGEMS, a proprietary, pliable tissue allograft (transplant) derived from human placental amnion, which functions as a biologic structural matrix to facilitate and enhance tissue healing and repair. AlphaGEMS contains 108 different growth factors including WNT-4 and prostaglandin.

Prostaglandin inhibits inflammation, which occurs after injury and marks the beginning of the healing process. The faster we can tame this inflammation, the sooner the body can move on to the next phase of healing, regeneration. It’s important to note that AlphaGEMS has more than 60 times the amount of prostaglandin compared to other products.

WNT4 is arguably the single most important molecule required for wound healing. AlphaGEMS has more than 10 times the amount of WNT4 as competing products.

About Tennis Elbow

Tennis elbow is an inflammation of the tendons that join the forearm muscles on the outside of the elbow. The forearm muscles and tendons become damaged from overuse — repeating the same motions again and again. This leads to pain and tenderness on the outside of the elbow.

About: Bone marrow injection: A novel treatment for tennis elbow



The objective of this prospective study was assessment of efficacy of bone marrow aspirate (BMA) (containing plasma rich in growth factors and mesenchymal stem cells) injection in treatment of tennis elbow.

Materials and Methods:

A total of 30 adult patients of previously untreated tennis elbow were administered single injection of BMA. This concentrate was made by centrifugation of iliac BMA at 2000 rpm for 20-30 min and only upper layer containing platelet rich plasma and mononuclear cells was injected. Assessment was performed at baseline, 2 weeks, 6 weeks and 12 weeks using Patient-rated Tennis Elbow Evaluation (PRTEE) score.


Baseline pre-injection mean PRTEE score was 72.8 ± 6.97 which decreased to a mean PRTEE score of 40.93 ± 5.94 after 2 weeks of injection which was highly significant (P < 0.0001). The mean PRTEE score at 6 week and 12 week follow-up was 24.46 ± 4.58 and 14.86 ± 3.48 respectively showing a highly significant decrease from baseline scores (P < 0.0001). Conclusion:

Treatment of tennis elbow patients with single injection of BMA showed a significant improvement in short to medium term follow-up. In future, such growth factors and/or stem cells based injection therapy can be developed as an alternative conservative treatment for patients of tennis elbow, especially who have failed non-operative treatment before surgical intervention is taken.

*Tissue used for AlphaGEMS is donated after normal, healthy births. Once it has been fully tested for infectious diseases, sterility and a few other things, the tissue is processed by using proprietary methods developed by Neil Riordan, PhD.

What are the sources of the stem cells used at Stem Cell Institute in Panama?

Lately, especially on our Facebook Page many people are asking us, “What is the source of the stem cells?”

Stem cells under fluorescent microscope.At the Stem Cell Institute, we use two types of stem cells. Primarily, we use allogeneic mesenchymal stem cells harvested from human umbilical cord tissue. In addition to allogeneic mesenchymal stem cells, our spinal cord injury protocol uses autologous (patient’s own) stem cells harvested from bone marrow.

Umbilical cord tissue is donated by mothers after normal, healthy births.

All donating mothers are tested for infectious diseases and have their medical histories screened. We obtain proper consent from each family prior to umbilical cord donation.

All mesenchymal stem cells harvested from umbilical cords are screened for infectious diseases to International Blood Bank Standards before they are approved for use in treatments.

A small number of umbilical cords (about 1 in 10) pass our rigorous screening process.

Dr. Riordan on the Umbilical Cord Selection Process at Stem Cell Institute

“Through retrospective analysis of our cases, we’ve identified proteins and genes that allow us to screen several hundred umbilical cord donations to find the ones that we know are most effective. We only use these cells and we call them ‘golden cells’.

We go through a very high throughput screening process to find cells that we know have the best anti-inflammatory activity, the best immune modulating capacity, and the best ability to stimulate regeneration.”

What are the advantages of treating with allogeneic human umbilical cord tissue (HUCT)-derived mesenchymal stem cells?

  • Anyone can be treated since HUCT mesenchymal stem cells are immune system privileged. Human Leukocyte Antigen (HLA) matching is not necessary.
  • The stem cells with the best anti-inflammatory activity, immune modulating capacity, and ability to stimulate regeneration can be screened and selected.
  • Allogeneic stem cells can be administered multiple times over the course of days in uniform dosages that contain high cell counts.
  • Umbilical cord tissue provides an abundant supply of mesenchymal stem cells.
  • No need to collect stem cells through invasive procedures such as liposuction or bone marrow collection
  • There is a growing body of evidence showing that mesenchymal stem cells from umbilical cords are more robust than mesenchymal stem cells from other sources such as fat.

The body’s immune system is unable to recognize human umbilical cord tissue (HUCT)-derived mesenchmyal stem cells as foreign and therefore they are not rejected. HUCT stem cells have been administered thousands of times at the Stem Cell Institute and there has never been a single instance rejection (graft vs. host disease). Umbilical cord-derived mesenchymal stem cells also proliferate/differentiate more efficiently than “older” cells, such as those found in the fat and therefore, they are considered to be more “potent”.

MS patient’s quality of life improvement “unbelievable” after stem cell therapy

Cathy Duke's Testimonial - with comment

“Thank you everyone for your kind words. Stem cells did not cure my MS, but they have improved my quality of life so much it is unbelievable. I have always had the support of my family and friends, and for this, I have been VERY appreciative. Stem cell therapy has given me a new quality of life and I thank God, my family and Dr. Neil Riordan at the Stem Cell Institute in Panama City, Panama. Life is good :-)”Cathy Miller Duke

“Last year on this day, my mom wasn’t able to participate in the Mackinac Bridge walk because, at exactly this time, she was in Panama receiving stem cell therapy, hoping it would improve her quality of life. Today, she was able to participate and walk that bridge…without a cane. (And apparently, she walked backwards a little jogged some too!) So proud of you mom!”Michelle Duke Thompson

PRESS RELEASE – Dallas-Fort Worth Stem Cell Researchers Use Amniotic Tissue To Successfully Treat Non-Healing Surgical Wound

Dallas-Fort Worth (PRWEB) August 28, 2015 – Riordan-McKenna Institute founders, stem cell expert Neil Riordan, PhD and orthopedic surgeon, Wade McKenna, DO, announced today that the use of sterile, dehydrated amniotic tissue AlphaPATCH™ developed by Amniotic Therapies in Dallas, Texas, resulted in complete healing of an otherwise non-healing surgical knee wound.

Before-After.262x175The case involved a 78-year-old male, who presented with a non-healing surgical wound following a right total knee replacement performed six weeks prior. The patient had not responded after 6 weeks of conservative wound care and the wound showed no signs of healing.

Dr. McKenna irrigated the wound in the operating room under pulse lavage and then placed two AlphaPATCH dry amniotic membranes (4 cm x 4 cm) over the wound before dressing it.

At the two-week follow-up visit, a central scab had formed. At four-weeks, the wound had completely scabbed over. At eight-weeks the scab had just fallen off and the wound was healing well with immature skin representing the size of a penny. At the ten-week follow-up visit, the wound was completely healed.

The case report, entitled “Case Report Of Non-Healing Surgical Wound Treated With Dehydrated Amniotic Membrane” is published in the July issue of the Journal of Translational Medicine. Authors include Dr. Riordan, Dr. McKenna, Troy Chandler, PA-C, and Ben George, PA-C. This milestone in Dr. Riordan and Dr. McKenna’s ongoing study of biologic wound healing using amniotic tissue products and stem cells is the third peer reviewed journal article on regenerative medicine published by the Riordan McKenna Institute.

A common misconception is that dehydrated amniotic membrane products like AlphaPATCH contain live stem cells. Although dehydrated amniotic membrane does not contain any stem cells, it does contain a number of growth factors that promote healing and stimulate the body’s own stem cells to become activated and likely behave more similar to stem cells in a younger person.

“It’s gratifying to have this new tool in my toolbox. I treated conservatively and was getting nowhere. Even in a patient with a significant smoking history and decreased blood flow to his legs, we were able to achieve this result. Chronic wounds can be very frustrating for both the patient and the caregiver,” remarked Troy Chandler, PA-C, who participated in the patient’s treatment.

After FDA Approval, Duchenne’s Muscular Dystrophy Patient Receives First Umbilical Cord Stem Cell Treatment in the United States

Ryan Benton, a 28 year-old Duchenne’s muscular dystrophy patient from Wichita, Kansas, received his first umbilical cord tissue-derived mesenchymal stem cell treatment yesterday at Asthma and Allergy Specialists of Wichita, KS following US FDA approval of his doctor’s application for a single patient, investigational new drug (IND) for compassionate use.

Ryan Benton

Ryan Benton, a 28 year-old Duchenne’s muscular dystrophy patient from Wichita, Kansas, received his first umbilical cord tissue-derived mesenchymal stem cell treatment yesterday following US FDA approval of his doctor’s application for a single patient, investigational new drug (IND) for compassionate use.

Duchenne muscular dystrophy (DMD) is a rapidly progressive form of muscular dystrophy that occurs primarily in boys. It is caused by an alteration (mutation) in a gene, called the DMD gene, which causes the muscles to stop producing the protein dystrophin. Individuals who have DMD experience progressive loss of muscle function and weakness, which begins in the lower limbs and leads to progressively worsening disability. Death usually occurs by age 25, typically from lung disorders. There is no known cure for DMD.

This trial, officially entitled “Allogeneic transplantation of human umbilical cord mesenchymal stem cells (UC-MSC) for a single male patient with Duchenne Muscular Dystrophy (DMD)” marks the first time the FDA has approved an investigational allogeneic stem cell treatment for Duchenne’s in the United States.

Ryan received his first intramuscular stem cell injections from allergy and immunology specialist, Van Strickland, M.D at Asthma and Allergy Specialists in Wichita, Kansas. He will receive 3 more treatments this week on consecutive days. Dr. Strickland will administer similar courses to Ryan every 6 months for a total of 3 years.

This is not the first time Ryan has undergone umbilical cord mesenchymal stem cell therapy. Since 2009, Ryan has been traveling to the Stem Cell Institute in Panama for similar treatments. Encouraging results from these treatments prompted Dr. Strickland to seek out a way to treat Ryan in the United States.

The stem cell technology being utilized in this trial was developed by renowned stem cell scientist Neil H. Riordan, PhD. Dr. Riordan is the founder and president of the Stem Cell Institute in Panama City, Panama and Medistem Panama. Medistem Panama is providing cell harvesting and banking services for their US-based cGMP laboratory partner.

Funding for this trial is being provided by the Aidan Foundation, a non-profit organization founded by Dr. Riordan in 2004 to provide financial assistance for alternative therapies to people like Ryan.

Neil Riordan PhD on stem cell expansion in stem cell therapy

Stem Cell Pioneers featured Dr. Riordan in its February installment of “Ask the Doctor”, a monthly segment that features stem cell scientists and doctors answering questions from readers about stem cell therapy.

Over the next several days, we will share these questions and Dr. Riordan’s answers with our readers.

Question: Are there some conditions such as neurological ones that respond better when the cells are greatly expanded? Is a high quantity essential for success or is that something that may be more of a selling point at some clinics? I have also seen this advertised for COPD and other conditions. It’s almost like the more cells the better, but I would like your opinion.

Dr. Riordan’s Answer: That really depends on the quality of the cells after expansion. If they are still robust, not senescent, and still have a good secretion profile, then the more the better may be useful up to a point. If you take a small pool of starter cells and expand them to exhaustion, then I don’t think you are going to have a very good product. The MSCs used in Panama are not expanded beyond passage 5—a point at which there is no senescence in the population and they have a robust cytokine secretion profile. In order to use only cells that meet our release criteria, cells from approximately one (1.2 to be exact) out of 10 donated umbilical cords are used.

Contrast that to cells from a patient’s own fat tissue that are expanded. Firstly, the starting cells may, and many times are not very robust—they secrete little or no beneficial cytokines or chemokines, and must be expanded to hilt in order to hit the cell number. Please see my answer to number 7 for more on this subject.

This brings up a slightly different, yet related topic. There has been a lot of talk at recent meetings about more defined endpoints for the cells being used, and I couldn’t agree more. There are MSCs from bone marrow, menstrual blood, fat tissue, umbilical cord (even different parts of the umbilical cord—around the blood vessels, from the Wharton’s jelly, from the subepithelium, from the cord blood itself—which are most likely contaminants from a bruised placenta rather than the blood), teeth, amniotic membrane, amniotic fluid just to name sources in the “we didn’t mess with mother nature” adult stem cell world. Add to that the infinite variables when you consider the age and physical condition of the donor, particularly when using adipose or bone marrow as a source material and we, as a field, could be saying almost anything by using the term, “mesenchymal stem cell.” I think it is time that there is standardization in the field beyond the current definition of expressing/not expressing certain surface markers and the ability to differentiate into fat, bone, and cartilage. That standardization could come from using endpoints such as “remaining proliferative capacity (the number of doublings achievable in culture from the treatment cell bank), the secretome, even if there is standardization of one or two molecules, such as HGF, or one of the prostaglandins.

In the future I believe the field will take it a step further by measuring, even by a surrogate marker, the potential effects of the cells on the target condition. In the case of autoimmunity the cells and their secretions could be tested for their capacity to modulate the immune system. In the case of inflammatory conditions, the cells and their secretions could be tested for the ability to control or block inflammation.

Umbilical Cord Stem Cells: Regeneration, Repair, Inflammation and Autoimmunity – Neil Riordan PhD (Part 2 of 2)

In part 2, Dr. Riordan discusses how mesenchymal stem cells can affect tissue repair in spinal cord injury and in heart failure; benefit to heart is not the actual MSCs modeling new tissue. It is due to the trophic effects of MSC secretions; In rats, severed spinal cords re-grew after MSCs were implanted but the human MSCs did not form new cord tissue. The trophic factors secreted by the MSCs enable the spinal cord to repair itself.; Trophic factors from MSCs modulate the immune system by blocking clonal expansion of cytotoxic T-cells; There are 35 ongoing clinical trials using mesenchymal stem cells for autoimmune diseases; Safety of donor MSCs; Every mother has MSCs from each baby she has carried; Mothers have a lower incidence of autoimmune disease; Lifespan of mothers increased linearly with each child up to 14; There are 85 ongoing clinical trials using donor MSCs. Allogeneic MSCs from bone marrow have been approved in Canada and New Zealand to treat graft vs. host disease; limbal cells used in corneal transplants are MSCs; MSCs are useful in preventing donated organ rejection; glioma growth was found to be inhibited by MSCs; MSCs eliminated breast cancer in rats.
