[Tissue culture course of a human hepatoma cell line].

A cell line, HuH-33 was cultured in vitro from a patient with hepatocellular carcinoma. This cell line has been in continuous culture over 12 month period with slow growth potential. HuH-33 was composed spindle-or polygonal-shaped cells as a major population. Chromosome number of the cells were widely distributed even in the primary culture. HuH-33 was transplantable into nude mice and secreted alpha-fetoprotein, albumin, beta 2 microglobulin, ferritin and tissue polypeptide antigen.
