Biological Activity for ITD 1
ITD 1 is a selective inhibitor of TGF-β signaling (IC50 = 0.85 μM); displays little or no inhibition of activin, Wnt or BMP signaling pathways. Induces proteasomal degradation of the TGF-β type II receptor. Inhibits TGF-β-induced mesoderm formation from mouse embryonic stem cells (ESCs) during early differentiation; selectively promotes the differentiation of ESCs to cardiomyocytes in vitro between days 3-5. Does not induce differentiation of vascular smooth muscle cells or endothelial cells.

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.
