title: Immunohistochemical reactivity of a monoclonal antibody prepared against human ovarian carcinoma on normal and pathological female genital tissues.
abstract: The reactivity profile of the monoclonal antibody (MAb) MOv18, raised against a poorly differentiated ovarian carcinoma specimen, was studied on normal tissues and tumors from the female reproductive system and on the kidney, which like the oviducts, vagina and uterus, also derives from the intermediate mesoderm. The obtained results indicate that MOv18 recognizes an epitope present on the normal epithelium of the oviducts, on 14-week old fetal kidney and, focally, on proximal and distal tubules of normal adult kidney. A strong reactivity was found on ovarian carcinomas, on invasive squamous carcinomas of the cervix and on endometrial carcinomas and hyperplasias. The antigen recognized by MOv18 (CaMOv18) therefore seems to be an epithelial cell marker associated with intermediate mesoderm differentiation, which can be derepressed during the neoplastic transformation of the ovary and the uterus.
