A small molecule promotor of hepatocyte differentiation
BRD-K4477, also known as functional hits 1 (FH1), is a small molecule promotor of hepatocyte differentiation in vitro.1 It induces maturation of hepatocyte-like cells (iHeps) to a more adult-like liver phenotype in a concentration-dependent manner. BRD-K4477 increases albumin secretion and promotes hepatocyte morphologies including polygonal cell shapes, visible nuclei, and formation of bile canaliculi in iHeps. It also increases expression of ABCB11 and bile-salt export pump (BSEP) mRNA as well as activity of the mature cytochrome P450 (CYP) isoforms CYP3A and CYP2A6 in iHeps.
