Dr. Arnold Caplan is a researcher at Case Western Reserve University and the father of modern stem cell therapy. His extensive work has shown that the regenerative materials used are predominantly acting as signals to one’s body, telling the body to “get to work” and repair itself.
Dr Caplan actually recommends changing the abbreviation of MSC’s, which normally stands for Mesenchymal Stem Cells, to Medicinal Signaling Cells. The goal is to “more accurately reflect the fact that these cells home in on sites of injury or disease and secrete bioactive factors that are immunomodulatory and trophic (regenerative) meaning that these cells make therapeutic drugs in situ that are medicinal.”
He continues, “It is, indeed, the patient’s own site-specific and tissue-specific resident stem cells that construct the new tissue as stimulated by the bioactive factors secreted by the exogenously supplied MSCs.”
