Isolation and characterization of rat fetal Sertoli cells

H Ueda, C Ziomek and PF Hall
Worcester Foundation for Experimental Biology, Shrewsbury, Massachusetts 01545.

Sertoli cells were prepared from fetal rats, aged 15, 18, and 21 days. Cultures of these cells can be prepared at a purity of 85% by a method that is widely used to prepare the same cells from postnatal rats. The fetal cells are identical in appearance to postnatal Sertoli cells. Fetal Sertoli cells round up in response to (Bu)2cAMP, but not in response to FSH. Protein synthesis in the cells is not stimulated by (Bu)2cAMP or FSH. However, incorporation of [35S]methionine into secreted proteins appearing in the incubation medium is stimulated by the cyclic nucleotide, but not by FSH. Reproducible patterns for the incorporation of [35S]methionine into cellular and secreted proteins are presented as autoradiograms of one- and two-dimensional electrophoretograms. These autoradiograms show that the response of secreted proteins to (Bu)2cAMP is a general one; most or all proteins participate in the response. No clear differences were observed in the nature of the proteins synthesized when cells from fetal rats of 15, 18, and 21 days of age were compared. Fetal Sertoli cells produced approximately 2 nmol lactate/10(6) cells.h, which is approximately one fifth of the amount produced by postnatal cells. Lactate production was increased by the addition of FSH or (Bu)2cAMP to the medium. Fetal Sertoli cells also synthesize androgen-binding protein, and this activity is not increased by either FSH or (Bu)2cAMP.
