title: Isolation of a metastasizing cancer cell line from an aflatoxin B1-induced rat liver tumor.
abstract: An attempt was made to isolate cancer cell lines from liver tumors that had been induced by aflatoxin B1 (AFB1) in rats. A clonal cell line named AFB-1 was isolated from a liver tumor that was histologically diagnosed as hepatocellular carcinoma. When AFB-1 cells were inoculated into the subcutaneous tissue at the dorsal region of syngenic animals, they metastasized from the site of inoculation into the abdominal cavity to form many tumor nodules throughout the serous membrane and metastatic foci in the kidney and pancreas. They also metastasized into the thoracic cavity to form metastatic foci in the lung. This is the first instance where a metastasizing AFB1-induced cancer cell line has been isolated.
