Ultrastructure of rat pinealocytes in vitro: Influence of gonadotropic hormones and LH-RH

Cell and Tissue Research Aims and scope Submit manuscript

Summary

The influence of gonadotropic hormones on the ultrastructure of rat pinealocytes in short-term organ culture was studied. Human chorionic gonadotropin (HCG), as well as pregnant mare serum gonadotropin (PMSG), caused a marked activation of pinealocytes. An hypothesis is discussed implying the presence of a feedback mechanism between the pineal organ and the hypothalamo-hypophysial system.
