Biological Activity for SANT-1
SANT-1 is a potent, cell-permeable inhibitor of Sonic hedgehog (Shh) signaling; high affinity antagonist of smoothened activity (KD = 1.2 nM). Inhibits smoothened agonist effects with an IC50 of 20 nM (in Shh-LIGHT2 cells). Has been used in protocols to generate pancreatic β cells from hPSCs.
For more information about how SANT-1 may be used, see our protocol: Generation of β cells from hPSCs

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.
Stem Cell Workflow Poster
Stem cells have potential as a source of cells and tissues for research and treatment of disease. This poster summarizes some key protocols demonstrating the use of small molecules across the stem cell workflow, from reprogramming, through self-renewal, storage and differentiation to verification. Advantages of using small molecules are also highlighted.
