Abstract：
:Hepatocytes from adult rats were cultured on poly-HEMA-coated surface to form spheroids in hormonally defined media as previously shown with newborn rat hepatocytes. Spheroidal aggregates of adult rat hepatocytes were morphologically similar to those of newborn rat hepatocytes and could also form a monolayer of uniform liver parenchyma-like cells when transferred on collagen-coated surfaces even after 2 months of culture. Under these culture conditions, albumin and transferrin secreted in vitro by adult rat hepatocyte spheroids were detectable by immunoprecipitation method at least until 2 months of culture. The production of proteins by hepatocyte spheroids could be regulated in vitro by IL-6: the secretion of alpha 2-macroglobulin was increased and the secretion of albumin was decreased in the presence of this cytokine. In addition, cytochrome P450 IA1 was strongly induced by methylcholanthrene in adult rat hepatocyte spheroids, and the induction remained relatively constant up to 22 days of culture. These cells were also able to metabolize lidocaine to monoethylglycinexylidine when measured up to 14 days of culture, showing the presence of a relatively high level of P450 IIIA2. The UDP-glucuronyltransferase activity, specific for bilirubin conjugation, decreased to 18% of the initial value after 2 weeks of culture. This work showed that adult rat hepatocytes in long-term spheroid culture kept differentiated functions, providing a new model for the in vitro study of hepatocyte functions and complementing that of newborn rat hepatocytes using the same system.
