title: Identification of human chorionic gonadotropin (HCG) secreting cells and other cell types using antibody to HCG and a new monoclonal antibody (mABlu-5) in cultures of human placental villi.
abstract: We have identified cells which secrete human chorionic gonadotropin (HCG) of cultures if first trimester placental villi. As a first step, we identified epithelial cells using a new monoclonal antibody. We then added HCG antibodies to the cultured cells. We found that syncytiotrophoblast (and not cytotrophoblast), Hofbauer cells and some mesenchymal cells stained with HCG antibodies.
