Abstract
The present invention is directed to methods for readily generating hepatocyte precursor cell lines that retain hepatocyte-specific functions after extensive in vitro culturing. The methods comprise isolating and culturing hepatocyte precursor cell lines under permissive culture conditions that suppress asymmetric cell kinetics and allow exponential growth of the precursor cells, followed by transferring the hepatocyte precursor cell lines to non-permissive culture conditions that allow expression of asymmetric cell kinetics and induce expression of hepatocyte-specific characteristics.
