Response of interstitial cells of the testes in the house musk shrew, Suncus murinus L., to various gonadotropins.
Testicular interstitial cells of the house musk shrew culture in vitro released testosterone in response to ovine LH with a quite similar dose response relationship to that found in the cells of rats. The dose response curves suggested that a single testicular cell of the shrew has the same potency to secrete testosterone as that of the rat. In the shrew as well as in the rat, neither ovine PRL added alone nor together with oLH could stimulate the testosterone release from testicular cells, although a very limited enhancement of testosterone secretion was observed in the cell cultured with a large dose of oFSH in both species.
