Assay Type: In Vitro
Species: Human
Cell Line/Tissue: Induced pluripotent stem cells

I used this product for differentiation of iPSCs into dopaminergic neurons according to the protocol published in Kriks et al, 2011.I used the concentration 10uM and it works really well.

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.
