Immunocytochemical localization of bioregulatory peptides in marmoset testes.
Immunocytochemical localization of neuropeptides (beta-endorphin, substance P, arginine vasopressin, oxytocin), pituitary hormones (adrenocorticotropin, prolactin, growth hormone, follicle stimulating hormone (FSH), gonadal inhibin, gastrin, and human chorionic gonadotrophin (hCG)) was carried out in marmoset testis during development. Both intensity of immunostaining and distribution of these peptides in testicular compartments viz. seminiferous tubules and Leydig cells changed dramatically during development. In vitro biosynthesis of inhibin and FSH was increased by hCG, whereas prolactin (5 micrograms) and prostatic inhibin peptide suppressed the synthesis of these hormones.
