Establishment and characterization of a serous papillary adenocarcinoma cell line of the human ovary in a serum-free culture.
In order to clarify the biologic characteristics of serous papillary adenocarcinoma of the human ovary, we tried to establish a continuous cell line using four primary tumor specimens derived from four patients with such tumors. We also evaluated c-myc, MYCN and c-erbB2 gene amplification in the cultured cells, and the xenografts, as well as in these four primary tissue specimens by a Southern blot analysis. One continuous cell line, named as FU-OV-1, was established in a serum-free culture system and this line propagated continuously for 96 serial passages over a 2-year-period in vitro. FU-OV-1 reproduced and still maintained the characteristics of the original tumor. C-myc gene amplification was found in the FU-OV-1 cells, and the xenografts, as well as in only the primary tumor of FU-OV-1 out of the four primary serous papillary adenocarcinomas. However, neither MYCN amplification nor c-erbB2 amplification was observed in any tumor specimens including FU-OV-1 cells. In conclusion, FU-OV-1 is thus considered to be a useful system for studying the biological behavior of serous papillary adenocarcinoma in the human ovary. The results of this study suggest that c-myc gene amplification might thus be associated with the progression of this tumor both in vitro and in vivo.
