What is RSC 133?

Description

RSC-133 is an indole compound that promotes the reprogramming of human somatic cells to pluripotent stem cells. Specifically, when used at 10 μM with four standard reprogramming factors, it increases the number of human foreskin fibroblasts that express the stem cell marker alkaline phosphatase. RSC-133 induces pluripotency by both down-regulating inducers of cellular senescence and inhibiting DNA methyltransferase and histone deacetylase activities.

The Uses of RSC 133

RSC 133 is a potent chemical booster for human somatic cell reprogramming. RSC 133 facilitates the maintenance of pluripotent human embryonic stem cells (hESCs) and human induced pluripotent stem cells (hiPSCs).
