A new cell line derived from a woodchuck hepatocellular carcinoma serially transplanted in athymic nude mice has been established and named WH257GE10. The original tumor in the nude mouse system produces woodchuck hepatitis surface antigen and albumin. In addition, woodchuck hepatitis virus DNA is i

β¦ Synopsis
Woodchucks free from woodchuck hepatitis virus were treated with diethylnitrosamine in vivo for 2 months, and then hepatocytes obtained by enzymatic perfusion were cultured with the hepatopromoter phenobarbital. This in vivo-in vitro procedure gave rise to proliferating epithelial cell foci, from one of which the presently described hepatocyte cell line (WLC-3) was established and characterized.
WLC-3 cells possess morphological and biochemical features of differentiated hepatocy$es, including glucose-6-phosphatase activity and albumin production. Histopathological analysis of the tumor which developed transitorily in nude mouse subcutis after inoculation of the cell line revealed glandular structures comprising cells of hepatocellular-like morphology.
This is the first established woodchuck hepatocyte cell line free from woodchuck hepatitis virus and is therefore expected to be useful for studying the mode of gene expression and viral proliferation of woodchuck hepatitis virus and the mechanisms underlying woodchuck hepatitis virus-related hepatocarcinogenesis.
Woodchuck (Marmota monux) is the natural host of the woodchuck hepatitis virus (WHV) which belongs to hepadnaviridae together with human hepatitis B virus (1). Like human hepatitis B virus carriers, WHV carrier animals are at very high risk of developing chronic hepatitis and hepatocellular carcinomas (HCCs) (2). The
