Complete reconstitution of mouse liver with xenogeneic hepatocytes.

Abstract excerpt

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,...
