[Establishment and characterization of a human hepatocellular carcinoma cell line JHH-4].

A human hepatocellular carcinoma cell line, JHH-4 was established from resected liver tumor. Morphological diagnosis of the original tumor was hepatocellular carcinoma, Edmondson type III. This cell line was composed of polygonal shaped cells. Subcellular organelle were observed in cytoplasm. Furthermore, bile canaliculi adhering junction was also remained at the cell surface. The growth rate of JHH-4 cell is slow, peaks of the chromosome number was 75 and 79, and plating efficiency was 3.0%. JHH-4 cell is transplantable to nude mouse. Furthermore, this cell line functionally synthesized and secreted human albumin, AFP and other proteins in vitro.
