Effects of gossypol on rat Sertoli and Leydig cells in primary culture and established cell lines

L. Z. Zhuang, D. M. Phillips, G. L. Gunsalus, C. W. Bardin and J. P. Mather

In order to evaluate the direct effect of gossypol on testicular cells, we used primary cultures of rat Leydig and Sertoli cells. No alteration in Leydig cell survival, morphology, or testosterone production was seen during three days of culture with up to 3 microgram/ml gossypol. With higher concentrations (3 to 7 microgram/ml) of gossypol, there was a reduction in cell survival but no change in androgen secretion. In contrast, there was a marked change in Sertoli cell morphology after five days of gossypol treatment. Large vacuoles and electron dense granules appeared in the cytoplasm, but these effects were reversed within six days of removing gossypol from the medium. There was a significant decrease in androgen binding protein (ABP) secretion by Sertoli cells in the presence of gossypol. We also tested the effect of gossypol on the growth of three established cell lines. Two Sertoli-derived cell lines, TM4 and TR-ST, were more sensitive than a Leydig-derived cell line (TM3). These results suggest that, of the somatic cell types in the testis, the Sertoli cells are most sensitive to gossypol.
