Mi-2/NuRD complex protects stem cell progeny from mitogenic Notch signaling.
To progress towards differentiation, progeny of stem cells need to extinguish expression of stem-cell maintenance genes. Failures in such mechanisms can drive tumorigenesis. In Drosophila neural stem cell (NSC) lineages...
