Professor Caplan is “The father of the mesenchymal stem cell (MSC)”. In this clip, he describes a mouse experiment using human MSCs in a mouse model of MS. The experiment shows that it’s possible to place human cells in mice that have normal immune systems. He continues to discuss the astounding results.

Abstract
OBJECTIVE:
HAART largely decreases morbidity and mortality in chronic HIV-1-infected patients, but immune nonresponders (INRs) with full viral suppression still fail to reverse the immune deficiency. This study evaluated the safety and immunological responses of human umbilical cord mesenchymal stem cell (MSC) therapy in HIV-1-infected INRs.
DESIGN AND METHODS:
A total of 13 HIV-1-infected INRs were enrolled in this pilot prospectively open-labeled controlled clinical trial. Seven patients were administered three umbilical cord-MSC transfusions at 1-month interval during 12-months of follow-up, whereas six control patients were treated with saline in parallel. Immunological parameters were monitored in these patients throughout the trial.
RESULTS:
All patients tolerated the umbilical cord-MSC transfusions well throughout the trial. The umbilical cord-MSC transfusions preferentially increased circulating naive and central memory CD4 T-cell counts and restored HIV-1-specific IFN-γ and IL-2 production in the INRs. These enhancements in immune reconstitution were also associated with the reduction of systemic immune activation and inflammation in vivo.
CONCLUSIONS:
umbilical cord-MSC transfusions are well tolerated and can efficiently improve host immune reconstitution in INRs, suggesting that such treatments may be used as a novel immunotherapeutic approach to reversing immune deficiency in HIV-1-infected INRs (ClinicalTrials.gov identifier: NCT01213186).
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.
Umbilical Cord Mesenchymal Stem Cells: Regeneration, Repair, Inflammation and Autoimmunity – Neil Riordan, PhD (Part 1 of 2)
Neil Riordan, PhD is the Founder of the Stem Cell Institute in Panama. He is also the Co-Founder of Medistem Inc in San Diego and the current President of Medistem Panama. Dr. Riordan is speaking at a Stem Cell Institute patient outreach event held in Miami in May 2013.
In part 1, Dr. Riordan discusses the background of Medistem Panama and the Stem Cell Institute (SCI) in Panama. He presents the types of stem cells used at SCI: Patient’s own bone marrow, Patient’s own fat tissue and umbilical cord mesenchymal stem cells donated from live, healthy births. Dr. Riordans goes on to discuss: collaborations with UC San Diego, Indiana University, University of Utah and University of Western Ontario; patents and publications; Medistem Panama lab, clean rooms and equipment; Why the Stem Cell Institute is in Panama; Panamanian stem cell laws; What are mesenchymal stem cells (MSCs) ?, mesenchymal stem cell homing, how MSCs induce repair, how MSCs modulate the immune system, young vs. old MSCs, Are MSCs safe?; MSCs are actually pericytes. They are found throughout the body in all vascular tissues around blood vessels, bone marrow, umbilical cord, placental tissue, menstrual blood and teeth; Stem Cell Institute’s source of umbilical cord MSCs: live, healthy birth, mother screened for medical history, consent from family for donation, mother tested for infectious diseases, cord tested for infectious diseases and sterility; the mesengenic process; how pericytes respond to injury and form “medicinal MSCs”; MSCs are anti-apoptotic, anti-scaring, angiogenic, and mitotic.; MSCs are also immunomodulatory; MSC homing in rats; Human MSCs decline drastically with age; Stem Cell Institute uses umbilical cord-derived MSCs because they are non-tumorigenic, very robust – high number of doublings, faster doubling time,; What does ‘doubling’ mean?; Effects of aging on MSCs.
