Abstract
We have developed a system for studying hepatocellular growth potential in which liver cells are introduced into the diseased livers of albumin-urokinase (Alb-uPA) transgenic mice. To use this system to study xenogeneic cell transplantation, rat liver cells were introduced into immunotolerant Alb-uPA transgenic mice. In regenerated recipient livers, up to 100% of hepatocellular gene expression was of rat origin, demonstrating the creation of a functional mouse liver in which parenchyma is derived from xenogeneic (rat) hepatocytes. Immunotolerant Alb-uPA transgenic mice provide a tool for studying hepatocellular biology of any species, including humans, in a controlled experimental setting.Keywords
