A Note on Clinical Trials for Stem Cell Therapies

Abstract

The rapid advance of stem cell clinical trials for a broad spectrum of conditions warrants an update of the review by Trounson [1]. There has been a rapid surge in clinical trials involving stem cell therapies over the last two to three years and those trials are establishing the clinical pathways for an emergent new medicine. These early trials are showing roles for stem cells both in replacing damaged tissue as well as in providing extracellular factors that can promote endogenous cellular salvage and replenishment.
