Abstract
Hedgehog signaling is essential for proliferation of neural precursor populations in the developing central nervous system (CNS) and is etiologic in cerebellar brain tumors. Here we will contrast general strategies of cell cycle regulation by growth factors in the developing CNS with the emerging concept of a noncanonical Hedgehog “proliferative pathway” as suggested by published studies. Mechanisms utilized by Sonic hedgehog signaling to promote cell cycle progression in CNS progenitors during development and in adult stem cell populations also contribute to CNS tumorigenesis.
