Description
Details
CHIR99021 is the most widely used, potent and selective inhibitor of glycogen synthase kinase 3 (GSK-3), inhibiting GSK-3β (IC50 = 6.7 nM) and GSK-3α (IC50 = 10 nM). It exhibits greater than 500-fold selectivity for GSK-3 over closely related kinases. CHIR99021 has been shown to enhance the reprogramming of murine and human somatic cells into iPSCs, potently promote expansion of ESCs and tissue-specific adult stem cells and induce differentiation of human ESCs/iPSCs toward neural or mesendoderm lineages under appropriate conditions.
