Abstract
This invention relates to virally-immortalized hepatocyte cell lines, which are derived from a normal primary human liver cell, have the ability to proliferate in a serum-free media, are nontumorigenic, and produce proteins. These cell lines can be used for toxicity testing of potential therapeutic drugs and chemical entities. The cell lines may also be used for the production of therapeutic plasma proteins.
