Estudo morfofuncional das células de Sertoli de ratos albinos tratados com etoposide na fase pré-púbere
(Universidade Federal de São Paulo (UNIFESP), 2006-12-31)
Spermatogenesis is a complex and controlled process in which Sertoli cells play a key role. In the testis, endocrine, paracrine and autocrine mechanisms that control spermatogenesis occurrence. The Sertoli cells synthesize ...
