Endogenous Nodal signaling regulates germ cell potency during mammalian testis development
4 Oct 2012
Abstract excerpt
Germ cells, the embryonic precursors of sperm or oocytes, respond to molecular cues that regulate their sex-specific development in the fetal gonads. In males in particular, the balance between continued proliferation and cell fate commitment is crucial: defects in proliferation result in insufficient spermatogonial stem cells for fertility, but escape from commitment and prolonged pluripotency can cause...
