Establishment and characterization of an endometrial adenocarcinoma cell line are described. The tumor cells, designated AC-258, originated from a patient with a poorly differentiated adenocarcinoma of the endometrium. These cells have been passed in culture more than 102 times and have maintained their morphological and chromosomal integrity in a fashion suggestive of monocloning. Cells from passages 1, 58, and 102 were aneuploid. The average number of chromosomes per cell was 64.8, and 8-17 marker chromosomes per cell were identified and described. Histological evaluation of tumor explants from 3 passages grown in nude (athymic) mice revealed morphologic identity. The doubling time of AC-258 was 22 hr. No detectable estrogen- or progesterone-binding proteins were found. The AC-258 cell line provides researchers with another tool with which to investigate biochemical and biological properties of human cancer cells.
