Since cultured cells have the possibility to produce tumor-associated substances in vitro, we generated several monoclonal antibodies using cultured cells as immunogen and applied them to cancer diagnosis. Two monoclonal antibodies (F602-1 and F602-6) were generated against a newly established ovarian mesonephroid cancer cell line (RMG-II), and a double determinants sandwich enzyme-immunoassay system was developed. Their epitopes were proved to exist on the CA125 molecules, but to be different from the one recognized by OC125, and almost the same result of serum assay as CA125 was obtained by this assay. A new monoclonal antibody (MSN-1) was produced by immunizing a new endometrial cancer cell line (SNG-II). MSN-1 recognized the Lewis-b carbohydrate moiety on the cell surface glycolipid, and seldom reacted immunohistochemically with normal endometrium, but reacted with about 90% of endometrial cancer cases. By application of MSN-1 to flow-cytometry, the possibility of differentiating endometrial normal cells from the cancer cells was demonstrated.

UI	MeSH Term	Description	Entries
D008649	Mesonephroma	A rare tumor of the female genital tract, most often the ovary, formerly considered to be derived from mesonephric rests. Two varieties are recognized: (1) clear cell carcinoma, so called because of its histologic resemblance to renal cell carcinoma, and now considered to be of muellerian duct derivation and (2) an embryonal tumor (called also ENDODERMAL SINUS TUMOR and yolk sac tumor), occurring chiefly in children. The latter variety may also arise in the testis. (Dorland, 27th ed)	Mesonephromas
D010051	Ovarian Neoplasms	Tumors or cancer of the OVARY. These neoplasms can be benign or malignant. They are classified according to the tissue of origin, such as the surface EPITHELIUM, the stromal endocrine cells, and the totipotent GERM CELLS.
