Abstract
We successfully established a breast scirrhous carcinoma cell line (designated as NABCA) derived from metastatic tumors of the lymph node. The cells grew as multi-layered cultures without contact inhibition. The population doubling time was approximately 66 h. G-band karyotype of NABCA revealed 66% diploid, XX. Surprisingly, the cells had a number of secretory granules and straight microvilli as a brash border. In heterotransplantation, the cells produced a tumor resembling the original tumor. The NABCA is sensitive to Adriamycin (doxorubicin; KYOWA HAKKO KOGYO, Tokyo, Japan) and Taxol (paclitaxel; Bristol-Myers KK, Tokyo, Japan). This cell line is useful for studying the mechanism of lymphatic metastasis and susceptibility of anticancer drugs in human breast scirrhous cancer.
