Small Molecules for Stem Cell Research
Y-27632 is a common research tool used in the field of stem cell research for maintenance, differentiation, and the survival of cells following cryopreservation. Y-27632 is also used as 3D growth matrix component and included in brain organoid differentiation media.
Y-27632 dihydrochloride is a highly specific inhibitor of Rho-associated coiled-coil protein kinase (ROCK) activity as a cell-permeable, ATP-competitive inhibitor of both ROCK1 (Ki of 220 nM) and ROCK2 (Ki 300 nM) (Ishizaki, et al.). Human embryonic stem cell (ESC) survival is improved through enhanced attachment following single cell dissociation, cryopreservation, and FACS sorting in both feeder-dependent and -independent cultures (Emre, et al.). This enhanced cell attachment, and thus recovery, is boosted through decreased dissociation-induced apoptosis (Watanabe, et al.). Y-27632 dihydrochloride primes human induced pluripotent stem cells (iPSCs) to selectively differentiate towards mesendodermal lineage via epithelial-mesenchymal transition-like modulation.
