Ciliobrevin A is a Hedgehog (Hh) pathway antagonist; blocks Sonic hedgehog (Shh)-induced Hh pathway activation (IC50 = 7 μM) downstream of Smo. Perturbs primary cilia formation; inhibits cytoplasmic AAA+ ATPase dynein-dependent microtubule gliding and ATPase activity.

This effectively inhibits Hh signaling. At 1 uM concentrations, we had satisfactory results with this compound.
Tested different concentrations and times for each cell for cilia imaging.

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 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.
