The Current Truth About Stem Cell Therapies By: Patrick McLaughlin, MD
Overview • History of MesenchymalStem Cells (MSCs) • Presumed Mechanism of Action: Past and Present • Current Truth About Stem Cell Therapies
Definition of Stem Cell • An undifferentiated cell of a multicellular organism which is capable of giving rise to indefinitely more cells of the same type, and from which certain other kinds of cell arise by differentiation.
Dr. Arnold Caplan, Phd.Director of Skeletal Research Center Case Western Reserve University
Culture Expansion and Transplantation Slide from Dr Applford and Dr Rathborne
Stem Cells are regulated by the FDA:You CAN NOT expand stem cells in culture

MSC – Based TherapyCaplan’s New Dogma • MSCs = Pericyctes (all tissues have them) • MSCsin vitro are multi-potent but NOT in vivo • Transplanted MSCsdock at sites of broken/inflamed blood vessels • MSC actions: • Immune component • Regenerative component MANAGEMENT OF THE BODIES INNATE REGENERATIVE CAPACITY
New Caplan Dogma • In Vivo, MSCs (aka Pericytes) DON NOT “REPLACE” DISEASED OR DAMAGED TISSUE • MSCs(aka Pericytes), WHEN INJECTED, DOC AT SITES OF BROKEN OR INFLAMMED BLOOD VESSELS AND MANAGE THE BODIES INNATE REGENERATIVE CAPACITY
The Truth About Stem Cell Treatments “THE EXACT MECHANISM IS UNKNOW”
Stem Cell Treatments Are Experimental!Clinical Results Are Varied • NO standardized preparation for clinical trials • Are all sources the same? • Is there a dose response? • Who will respond to therapy? (early is better) • What is the best application? • My hope…
