Cyclical expression of GDNF is required for spermatogonial stem cell homeostasis
14 Feb 2018
Abstract excerpt
ABSTRACT In the murine testis, self-renewal of spermatogonial stem cells (SSCs) requires glial cell line-derived neurotrophic factor (GDNF) secreted from neighboring somatic cells. However, it not clear how GDNF promotes self-renewal in vivo or what downstream signaling pathways are required for SSC maintenance. We found that GDNF is normally expressed cyclically during spermatogenesis. Stage-specific ectopic...
