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 expansin 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.

Biopharmaceutical Executive Dr. Alan Lewis Appointed as CEO of Medistem
World-Class Industry Expert to Accelerate Commercialization of Universal Donor Stem Cell Drug for Heart Failure, Critical Limb Ischemia and Type 1 Diabetes


SAN DIEGO, CA--(Marketwire - Oct 9th 2012) - Medistem Inc. (PINKSHEETS: MEDS) announced today appointment of Dr. Alan Lewis to the position of Chief Executive Officer and Member of the Board. Since January, Dr. Lewis has been functioning in the capacity of Scientific Advisory Board Member for Medistem.

"We are enthusiastic that Dr. Lewis is taking the helm to help accelerate clinical development of the Endometrial Regenerative Cell (ERC) universal donor stem cell product, which is already a Phase I and Phase II studies for critical limb ischemia and congestive heart failure, respectively." Said Dr. Vladimir Bogin, Chairman of Medistem. "Dr. Thomas Ichim is assuming the role as the company's President and Chief Scientific Officer."

Dr. Lewis spent 15 years at the pharmaceutical company Wyeth-Ayerst, where he was Vice President of Research, leading translational research efforts in diabetes, CNS, cardiovascular, inflammatory, allergy and bone metabolism diseases. He subsequently became CEO of Signal Pharmaceuticals, a drug development company that he successfully merged with Celgene. He became CEO of Novocell Inc (Viacyte) and subsequently served as CEO of the Juvenile Diabetes Research Foundation, the largest research funding body for diabetes.

Your Body's Stem Cell Bank Account

By Neil Riordan, PhD

Everybody is born with a certain amount of stem cells, specifically, "adult stem cells." This number may be thought of as a type of "bank account", from which each person may make "withdrawals" throughout his or her lifetime, as needed.

However, not all bank accounts are created equal. To continue with the analogy, some people are born rich, while others are born poor. Most people, however, may be thought of as "middle class." This fact helps to explain why some people are able to enjoy health and longevity despite very unhealthy lifestyles, while other people may enjoy neither robust health nor longevity despite healthy lifestyles. In other words, some people are able to "spend" their stem cells more extravagantly than others, simply because they have more to spend. Most of us, however, fall somewhere in the middle, where both the length and the quality of our lives may be influenced to some degree by our choice of lifestyle. Environmental factors also play a key role in determining how rapidly one's "bank account" of (adult) stem cells is depleted. However, even under ideal circumstances, stem cells continually diminish with age.

Our stem cells exist in every part of the body to repair damage, such as from broken bones, a paper cut, radiological or chemical exposure, etc., all of which require stem cells for healing. You may draw on your bank account at any time, whenever you need to do so, until you run out of stem cells. As your "bank account" of stem cells approaches zero, physiological healing will become increasingly difficult, until finally it ceases altogether.

Utilizing stem cells is like going to the ATM machine. Depending upon how you live your life, and whether you were born with a large or a small bank account of stem cells, you either may or may not be able to withdraw from your account. If you were fortunate enough to be born with a large amount of stem cells, then you might possibly be able to smoke and drink and eat unhealthy food and never exercise, and still live to a ripe old age, because regardless of how many stem cells you expend, there are still more to be spent.

On the other hand, if you were born at the opposite end of the spectrum, with a small amount of stem cells, then an unhealthy lifestyle will have a more immediate and detrimental impact upon the quality and length of your life. This is known as Nature's Law of Conservancy: the less stem cells that exist in your "account", the more stingy the ATM machine becomes in distributing the contents of that account. Most people, however, are born into the stem cell "middle class", which is to say that lifestyle choices can often make a noticeable difference in determining health and longevity.

When someone has a large number of stem cells in the bank, the ATM works very quickly and efficiently. But when the bank account is almost empty, which ordinarily happens in the latter years of life, the ATM machine does not distribute the stem cells as readily. In biological terms, this is because the division rate of the cells has slowed considerably. Simply changing the doubling time of stem cells from 24 hours to 72 hours can make a 90-day difference in the amount of time required to reach a "critical mass" of cells that are required to heal a wound. Michael Andreeff, M.D., Ph.D., a professor in the Departments of Blood and Marrow Transplantation and Leukemia Cancer at M.D. Anderson, has described cancer as a "never healing wound"; in some cases, the doubling time of the stem cells may never be fast enough to "catch up" and heal the wound. This is why the incidence of cancer increases with age. After childhood cancers (which arise due to genetic factors or to overwhelming environmental exposure), the incidence of cancer drops significantly until around the age of 40, when it starts to increase, shooting up dramatically around the age of 50, and then falling again around the age of 65.

When someone has fully depleted his or her stem cell reserve, the only possible way to get more stem cells is from an alternate source. This is where stem cell therapy comes into play.


Salamanders are a supreme example of stem cell billionaires. Salamanders have a seemingly unlimited supply of stem cells, as their "bank accounts" are virtually incapable of being depleted. If you were to look at the blood of a salamander under a microscope, you would see that all of the red blood cells (RBCs) are nucleated. In other words, all RBCs of a salamander contain nuclei, unlike human RBCs, which are not nucleated. This is why salamanders can regenerate entire limbs and humans cannot: every RBC in a salamander is a functional stem cell, floating around everywhere throughout the salamander's body. In humans, by contrast, our RBCs cannot replicate themselves once they have migrated out of our bone marrow. As long as the salamander is still alive, its ATM machine is fast and generous in distributing as many stem cells as may be needed for any task.

Although humans are not salamanders, the ability to regenerate entire limbs nevertheless offers a powerful example of the possible applications and implications of stem cells. Practically as well as theoretically, an enormous, mostly untapped, potential exists in the field of stem cell therapy.

Medistem Achieves Important ERC Stem Cell Clinical Trial Milestone

More progress reported on the treatment of heart disease with endometrial stem cells. Neil Riordan, PhD is one of the early pioneers of endometrial stem cell technology. Dr. Riordan is also the Founder and President of the Stem Cell Institute in Panama City, Panama.

Positive Two-Month Data From RECOVER-ERC Congestive Heart Failure Trial

SAN DIEGO, CA--(Marketwire - Jun 4, 2012) - Medistem Inc. (PINKSHEETS: MEDS) announced today positive safety data from the first 5 patients enrolled in the Non-Revascularizable IschEmic Cardiomyopathy treated with Retrograde COronary Sinus Venous DElivery of Cell TheRapy (RECOVER-ERC) trial. The clinical trial uses the company's "Universal Donor" Endometrial Regenerative Cells (ERC) to treat Congestive Heart Failure (CHF).

According to the study design, after 5 patients enter the trial, they must be observed for a two month time period before additional patients are allowed to enter the study. Patient data was analyzed by the study's independent Data Safety Monitoring Board (DSMB), which concluded that based on lack of adverse effects, the study be allowed to continue recruitment.

"Medistem is developing a treatment for CHF that uses a 30-minute catheter-based procedure to administer the ERC stem cell into the patients' hearts. The achievement of 2 month patient follow-up with no adverse events is a strong signal for us that our new approach to this terrible condition is feasible," said Thomas Ichim, CEO of Medistem.

The RECOVER-ERC trial will treat a total of 60 patients with end-stage heart failure with three concentrations of ERC stem cells or placebo. The clinical trial is being conducted by Dr. Leo Bockeria, Chairman of the Backulev Centre for Cardiovascular Surgery, in collaboration with Dr. Amit Patel, Director of Clinical Regenerative Medicine at University of Utah.

"As a professional drug developer, I am very optimistic of a stem cell product that can be used as a drug. The ERC stem cell can be stored frozen indefinitely, does not need matching with donors, and can be injected in a simple 30-minute procedure into the heart," said Dr. Sergey Sablin, Vice President of Medistem and co-founder of the multi-billion dollar NASDAQ company Medivation.

Currently patients with end-stage heart failure, such as the ones enrolled in the RECOVER-ERC study, have no option except for heart transplantation, which is limited by side effects and lack of donors. In contrast to other stem cells, ERC can be manufactured inexpensively, do not require tissue matching, and can be administered in a minimally-invasive manner. Animal experiments suggest ERC are more potent than other stem cell sources at restoring heart function. The FDA has approved a clinical trial of ERC in treatment of critical limb ischemia in the USA.

Legendary Texas Football Coach and Stem Cell Recipient Sam Harrell Returns to Coaching

In 2010, the debilitating effects of multiple sclerosis forced Sam Harrell to retire from his position as Head Football Coach at Ennis High School. But after receiving 3 courses of stem cell therapy at the Stem Cell Institute in Panama, Sam is returning to the gridiron once again.

Brownwood Lion Head Coach, Bob Shipley announced that Harrell will be joining the team as quarterback coach. Sam coached all three of his sons at Ennis High School, most notably his son Graham Harrell. Graham was a standout quarterback at Texas Tech and now plays for the Green Bay Packers.

During his career at Ennis, Harrell pioneered the spread offense that led the team to three Texas state championships.

"I told the kids this morning," said Coach Shipley when asked about how he addressed the team, "And I didn't have to explain who Sam Harrell was, they knew. And they just erupted in applause and they were just looking at each other with their jaws dropped open, like they couldn't believe that Coach Harrell was going to come and be apart of our staff."

"Sam just really liked the thought of coming and not being the head coach and not being the offensive coordinator, but just coaching the quarterbacks, which is really what his passion is."

The Stem Cell Institute was founded in 2005 by Neil Riordan PhD and has treated over 1,500 patients to-date. Find out more about stem cell therapy for MS at www.cellmedicine.com
