Establishment and characterization of human uterine poorly differentiated adenocarcinoma cell line (HHUABM)

The cell line designated HHUABM was established from the metastatic region (left Bartholin gland) of human endometrial adenocarcinoma. The cell line grew well, multilayering rapidly without contact inhibition, and 72 serial passages were successively done within 25 months. The cultured cells of HHUABM line were round and spindle in shape, and showed a pavement-like arrangement. The distribution of chromosome number varied narrowly at the diploid range, and the modal chromosome number was 46. The 90% of metaphase cells showed normal karyotype. The HHUABM cells were transplanted easily into the subcutis of BALB/c nude mice and produced poorly differentiated adenocarcinoma resembling the original tumor. The conditioned medium promoted the proliferation of CPAE (endothelial cells). The estradiol-17 beta and progesterone receptors were not detected.
