Establishment and characterization of a cell line derived from human ovarian mucinous cystadenocarcinoma / 中华妇产科杂志

ABSTRACT

Objective To establish a cell line of human ovarian cancer, and study its characterization. Methods The cell line was established by the cultivation of subsides walls, and kept by freezing. The morphology was observed by microscope and electromicroscope. The authors studied its growth and propagation, the agglutination test of phytohemagglutinin (PHA), the chromosome analysis, heterotransplanting, immuno histochemistry staining, the analysis of hormone, the pollution examination and the test of sensitivity to virus etc. Results A new human ovarian carcinoma cell line, designated ovarian mucinous cystadenocarcinoma 685 (OMC685), was established from mucinous cystadenocarcinoma. This cell line had subcultured to 91 generations, and some had been frozen for 8 years and revived, still grew well. This cell line possessed the feature of glandular epithelium cancer cell. The cells grew exuberantly, and the agglutinating test of PHA was positive. Karyotype was subtriploid with distortion. Heterotransplantations,alcian blue periobic acid schiff (AbPAS),mucicarmine,alcian blue stainings, estradiol (E 2) and progesterone were all positive. Without being polluted, it was sensitive to poliovirus Ⅰ, adenovirus 7 and measles virus. Conclusions OMC685 is a distinct human ovarian tumous cell line.
