VIDEO – The Science of Mesenchymal Stem Cells and Regenerative Medicine – Arnold Caplan PhD (Part 6)

In part 6, Prof. Caplan discusses Trophic properties of mesenchymal stem cells; MSCs for heart disease; MSCs homing to heart injury site and also to skin incision site; MSCs limit left ventricular thinning following infarction; Trophic properties of MSCs: anti-apoptotic, anti-fibrotic, anti-scarring, angiogenic, mitotic; phase 1 data for allogeneic MSCs show fewer arrhythmias, prompt heart rate recovery, and improved lung function; autologous adipose tissue-derived stromal vascular fraction for treatment of chronic heart disease; Active mesenchymal stem cell clinical trials around the world; Induction therapy with autologous MSCs in kidney transplants; MSCs can coax neural stem cells to become oligodendrocytes, curing mice with MS using allogeneic human MSCs.

The Science of Mesenchymal Stem Cells and Regenerative Medicine – Arnold Caplan PhD (VIDEO Part 2)

In Part 2, Prof. Caplan discusses the two types of regenerative medicine: tissue engineering and in vivo tissue regeneration, hematapoietic and mesenchymal stem cells. All mesenchymal stem cells are pericytes and have immuno-modulatory and trophic properties

Prof. Caplan was speaking in Panama City, Panama at “La Medicina Del Futuro En El Presente”, an event organized by the honarable Ruben Berrocal MD, Minister of Science, Technology and Innovation SENACYT (National Secretariat of Science, Technology and Innovation) and Prof. K. S. Jagannatha Rao, Ph.D., FNASc, FABAP, FASB, FLS (Reino Unido) Director INDICASAT-AIP (Instituto de Investigaciones Cientificas y Servicios de Alta Tecnologia — Institute for Scientific Research and High Technology Services).

Case studies of spinal cord injury patients treated with CD34+ and mesenchymal stem cells harvested from human umbilical cord Wharton’s jelly and cord blood, animal studies using mesenchymal stem cells, immunosuppression requirements in allogeneic stem cell treatments, intrathecal and intravenous administration of autologous bone marrow stem cells in spinal cord injury patients, and the role adult stem cell trophic factors in tissue regeneration.

Multiple Sclerosis Treatment Success Using Mesenchymal Stem Cell-Secreted Factors in Animal Model

Stem cell researchers at Case Western Reserve have reported in Nature Magazine that the functional deficits caused by multiple sclerosis can be reduced by administering mesenchymal stem cell secreted factors.

While previous studies have shown promising results using mesenchymal stem cells, this is the first time that such results have been reported without using the stem cells themselves.

The Stem Cell Institute’s Founder, Neil Riordan PhD, originally cited the potential therapeutic role of mesenchymal stem cell trophic factors in the 2010 Cellular Immunology publication: Mesenchymal Stem Cells as Anti-inflammatories: Implications for Treatment of Duchenne Muscular Dystrophy

In addition to reducing functional deficits, the development of new myelinating oligodendrocytes and neurons, release of inflammatory cytokines, and suppression of immune cells influx were also observed in the Case Western study.

Mesenchymal stem cells (MSCs) have emerged as a potential therapy for a range of neural insults. In animal models of multiple sclerosis, an autoimmune disease that targets oligodendrocytes and myelin, treatment with human MSCs results in functional improvement that reflects both modulation of the immune response and myelin repair. Here we demonstrate that conditioned medium from human MSCs (MSC-CM) reduces functional deficits in mouse MOG35–55-induced experimental autoimmune encephalomyelitis (EAE) and promotes the development of oligodendrocytes and neurons. Functional assays identified hepatocyte growth factor (HGF) and its primary receptor cMet as critical in MSC-stimulated recovery in EAE, neural cell development and remyelination. Active MSC-CM contained HGF, and exogenously supplied HGF promoted recovery in EAE, whereas cMet and antibodies to HGF blocked the functional recovery mediated by HGF and MSC-CM. Systemic treatment with HGF markedly accelerated remyelination in lysolecithin-induced rat dorsal spinal cord lesions and in slice cultures. Together these data strongly implicate HGF in mediating MSC-stimulated functional recovery in animal models of multiple sclerosis.
