Small Molecules for Stem Cell Research
RepSox is a potent and selective inhibitor of the TGF-β type 1 receptor (TGFβRI)/ALK5 that exhibits cell permeability and specifically inhibits ALK5 autophosphorylation with IC50 of 4 nM. When used in conjunction with CHIR99021, LDN193189, and Y27632, among others, RepSox aids in the generation of functional human pancreatic beta cells from human pluripotent stem cells (PSCs) (Pagliuca, et al.). RepSox has also been shown to contribute to the reprogramming of mouse embryonic fibroblasts to iPSCs (Subramanyam, et al.), in addition to the induction of human fibroblasts into neuronal cells for research on Alzheimer’s disease (Hu, et al).
