Résumé :

Localization of human chorionic somatomammotrophin (HCS) has been studied in seventeen normal human placentas, obtained between 6 and 40 weeks of gestation by an immuno-histochemical technique using peroxidase labeled antibodies. A positive immunoreaction was found in the cytoplasm of the syncytiotrophoblast of the villi, of multinucleated giant cells of the basal plate and of several non langhansian cytotrophoblastic cells (chorionic cytotrophoblast, cytotrophoblastic shell and columns, recurrent cytotrophoblastic cells). The cytoplasm of some cells of the amniotic epithelium were also strongly positive, indicating the presence of HCS.
