Suppressor of Fused regulates the proliferation of postnatal neural stem and precursor cells via a Gli3-dependent mechanism.

ABSTRACT: The ventricular-subventricular zone (V-SVZ) of the forebrain is the source of neurogenic stem/precursor cells for adaptive and homeostatic needs throughout the life of most mammals. Here, we report that Suppressor of Fused (Sufu) plays a critical role in the establishment of the V-SVZ at early neonatal stages by controlling the proliferation of distinct subpopulations of stem/precursor cells. Conditional deletion of Sufu in radial glial progenitor cells (RGCs) at E13.5 resulted in a dramatic increase in the proliferation of Sox2+ Type B1 cells. In contrast, we found a significant decrease in Gsx2+ and a more dramatic decrease in Tbr2+ transit amplifying cells (TACs) indicating that innate differences between dorsal and ventral forebrain derived Type B1 cells influence Sufu function.
