Abstract
Differentiation of seminiferous cords can be obtained in in vitro cultures in a synthetic medium of undifferentiated fetal rat gonads. In older testes the seminiferous cords are maintained under these conditions. Adding 15% fetal calf serum to the medium prevents the differentiation of the seminiferous cords or provokes the disruption of the already formed cords (days 14 and 15). These actions are exerted upon the fetal Sertoli cells.
