A small molecule that can maintain the self-renewal of mESC (murine embryonic stem cells) in the absence of feeder cells and exogenous factors.
Description :
A small molecule that can maintain the self-renewal of mESC (murine embryonic stem cells) in the absence of feeder cells and exogenous factors; works through dual inhibition of RasGAP and ERK1; maintains the undifferentiated phenotype of mES cells with EC50 of 1 uM, and shows low cellular toxicity (>30 uM).
Pluripotin (SC-1) inhibits Abl1, p70S6K, PLK2, RSK1, RSK2, RSK3, RSK4 with IC50s of 0.005, 1.4, 2.2, 0.5, 2.5, 3.3, 10.0 µM,respectively. Pluripotin (SC-1) decreases cell growth for 7 colon tumor cell lines. After a five day exposure to 0.1 µM SC-1, the seven colon tumor lines are evaluated for changes in cell number and viability. There is a statistically significant decrease in cell number but >95% viability[2].
SC1 is a dual function small molecule inhibitor of both ERK1 and RasGAP and that simultaneous inhibition of both protein activities is required and sufficient for SC1’s effects on mES cells. SC1 activates Ras by inhibition of RasGAP function[1]. SC1 improved the derivation efficiency and pluripotency of ES cells from C57BL/6. Three types of pluripotent stem cells (fES, ntES, and iPS cells) of the C57BL/6 background could generate full-term pups with high efficiency when cultured with SC1[3].
