Stem Cells Scientific Review

Written by Kirsty E. Clarke, Victoria B. Christie, Andy Whiting and Stefan A. Przyborski, this review provides an overview of the use of small molecules in the control of stem cell growth and differentiation. Key signaling pathways are highlighted, and the regulation of ES cell self-renewal and somatic cell reprogramming is discussed. Compounds available from Tocris are listed.
