General description

hCG is a protein secreted in large quantities by normal trophoblasts; the antibody detects cells and tumors of trophoblastic origin such as choriocarcinoma. Large cell carcinoma and adenocarcinoma of the lung demonstrate anti-hCG positivity in 90% and 60% of cases respectively. 20% of lung squamous cell carcinomas are positive for anti-hCG. hCG expression by non-trophoblastic tumors may indicate aggressive behavior since it has been observed that hCG may play a role in the host response to a given tumor.

The authors studied the expression of trophoblastic cell markers in lung carcinomas cells by immunoperoxidase staining using antibodies against three trophoblastic glycoproteins (human chorionic gonadotropin [hCG]; human placental lactogen [hPL]; pregnancy-specific beta 1-glycoprotein [SP-1]). One hundred five tissue sections from...

This report presents preliminary observations on the immunocytochemical localization of human chorionic gonadotropin (hCG) and human placental lactogen (hPL) in placental site trophoblastic tumors, hydatidiform moles, and choriocarcinomas and compares the findings with those of a similar immunocytochemical analysis of...

The calcium-regulating enzyme calcium adenosine triphosphatase (Ca-ATPase) was localized in the epithelium of amphibian urinary bladder by the one-step electron microscopic cytochemical procedure. The enzyme was identified along the basolateral border of the epithelial cells that comprise the bladder mucosa....
