Characterization of Human Mesenchymal Stem Cells

Human mesenchymal stem cells (hMSCs) are a self-renewing population of adherent, multipotent progenitor cells that can differentiate into several lineages. The current definition of MSCs includes adherence to standard tissue culture plastic ware, expression of various surface antigens, and multilineage in vitro differentiation potential (osteogenic, chondrogenic, and adipogenic). hMSCs hold great promise as therapeutic agents because of their potential ability to replace damaged tissue and their immunomodulatory properties. Consequently, many clinical trials using hMSCs are currently under way in a…

Advocating an Evolution

In a 2006 report, the US Department of Health and Human Services hailed regenerative medicine as “the vanguard of 21st century healthcare” and “the first truly interdisciplinary field that utilizes and brings together nearly every field in science” (1). To fuel support for regulatory, legislative, and reimbursement initiatives in this new therapeutic class, a small group of scientists, life science business executives, patient advocates, and other experts formed the Alliance for Regenerative Medicine (ARM, http://alliancerm.org). Starting with 17 charter members,…
