Molecular Mechanisms Controlling Sertoli Cell Proliferation and Differentiation

Abstract excerpt

Whereas spermatogonia stem cells continually divide to populate the testis with developing germ cells, the major supporter of this process, the Sertoli cell, ceases to proliferate shortly after birth in rodents and during puberty in higher primates including men. Because Sertoli cells are capable of supporting only a fixed number of germ cells, the timing of Sertoli cell exit from the cell cycle, and therefore...
