CHIR99021
Size: 10 mg
Small Molecules for Stem Cell Research
CHIR99021 is a highly-potent and -selective inhibitor of GSK3α (IC50 of 10) and GSK3β (IC50 of 6.7), exhibiting over 500-fold selectivity when compared to its nearest homologs. CHIR99021 has been an effective component within differentiation protocols of pluripotent stem cells (PSCs) into human pancreatic beta cells (Pagliuca, et al.), neural progenitor cells (Li, et al. & Qi, et al.), cardiovascular progenitor cells (Cao, et al.), and functional cardiomyocytes (Lian, et al. & Burridge, et al.).
Additionally, CHIR99021 has been shown to promote the induction of human PSCs (Li, W. et al.) and self-renewal of PSCS for maintenance purposes (Ying, et al.).
