The bodies have much greater potential to regulate spermatogonial stem cell proliferation and differentiation. The dosage of GFRα1 mRNA produced by undifferential spermatogonial cells regulates the signal transduction of glial cell-derived neurotrophic factor so as to regulates the direction of spermato gonial stem cells: at a low level, spermatogonoial stem cell favors differentiation; at a high level, spermatogonial stem cell favors self-proliferation.
