The human hepatocellular carcinoma cell line PLC/PRF/5, which synthesizes and secretes hepatitis B surface antigen, was grown under optimal conditions in tissue culture, using Eagle's minimal essential medium supplemented with 10% fetal bovine serum and 10(-11) M triiodothyronine on collagen rafts. Injection s.c. of the PLC/PRF/5 cell line into athymic BALB/c nude mice resulted in the growth of a well-circumscribed, moderately differentiated hepatocellular carcinoma. The intervals until tumor appearance and tumor "take" rates were dependent on inoculum dose. Four to 5 x 10(6) cells induced tumor growth in 29% of 14 injected mice within 29 to 40 days, while 7 to 13 X 10(6) cells induced tumors in all 15 mice within 10 to 12 days after inoculation. Hepatitis B surface antigen was detected in the nude mouse serum and tumor tissue, and its concentration roughly correlated with tumor weight. A low level of antibody against hepatitis B surface antigen was detected in five tumor-bearing animals, as well as in one mouse which did not produce a tumor. Hepatitis B core antigen and its antibody and hepatitis B e antigen and its antibody were not detected in 26 mice, using immunohistochemical and radioimmunoassay methods. alpha-Fetoprotein, carcinoembryonic antigen, and alpha-antitrypsin were detected in nude mice tumors, using the peroxidase-antiperoxidase technique. Finally, hepatitis B virus DNA, identified in the nude mouse tumor by molecular hybridization techniques, was compared to PLC/PRF/5 cell line hepatitis B virus DNA.
