SCF inhibits caspase-8 and caspase-3 activation induced by IFNγ and/or FasL.

Day −6 ECFCs were incubated in medium with or without IFNγ (400 U/mL), FasL(50 ng/mL), or SCF (100 ng/mL) for 72 hours. Cell protein lysates were prepared, and immunoblot analyses were performed with anticaspase-8 and anticaspase-3 antibodies.
