Abstract: Testicular peritubular cells produce paracrine mediators which modulate Sertoli cell function. The production of these mediators (P Mod-S) is controlled by androgens suggesting that mesenchymal-epithelial interactions play an important role in androgen action in the testis. We investigated whether mesenchymal cells from the prostate, another androgen target tissue, produce analogous mediators. To this end rat Sertoli cell cultures were exposed to dialyzed spent media derived from testicular peritubular cells, prostatic stromal cells or footsole fibroblasts. It is demonstrated that the effects of spent media from peritubular cells and stromal cells are nearly identical: they stimulate the production of androgen binding protein and transferrin and they inhibit FSH-inducible aromatase activity. The active principle (or principles) involved is non-dialyzable, heat sensitive and trypsin sensitive. Its production is markedly stimulated by androgens. Fibroblast spent media are inactive. It is concluded that mesenchymal tissue derived from different androgen target tissues may produce identical or similar mediators of androgen action acting on epithelial cells.
