In vitro interactions between Sertoli cells and steroidogenic cells.
Both the cell and the species specificities of the steroidogenic potentiating activity (SPA) of Sertoli cells on Leydig cells were studied using a coculture system. Coculture of purified pig Leydig cells with rat or pig Sertoli cells in the presence of FSH led in both cases, to a significant increase in hCG receptor number and in hCG-stimulated testosterone production. Similarly, coculture of bovine adrenal cells with rat or pig Sertoli cells enhanced the steroidogenic response of adrenal cells to ACTH and angiotensin II. Such effects were not observed when pig Leydig cells or bovine adrenal cells were cocultured with bovine aortic endothelial cells. Coculture of Sertoli and Leydig cells in the presence of hCG, resulted in a significant increase in FSH receptor number and in FSH- induced plasminogen activator activity. Such effects did not occur when Sertoli cells were cocultured with either adrenal or aortic endothelial cells.[1]References
