Characterization of a Human Carcinosarcoma Cell Line of the Ovary Established after in Vivo Change of Histologic Differentiation

2001

Abstract Objectives. Cell lines are valuable in vitro models for clinical and basic research. Most ovarian cancer cell lines described are serous cystadenocarcinomas or poorly differentiated adenocarcinomas. The establishment of ovarian cancer cell lines with rare histologic differentiation is especially of interest. We describe the establishment of a carcinosarcoma cell line of the ovary after in vivo selection. Methods. The cell line OV-MZ-22 was established from a solid tumor mass in the upper abdomen. At the time of establishment, the patient underwent secondary debulking and was pretreated with six cycles of cis -platinum/epirubicin/cyclophosphamide. Features of the cell line studied i…
