ALB and Fulminant hepatic failure: After transplanting human immature hepatocytes, including human primary FLCs and human HpSCs, into Alb-TRECK/SCID mice with lethal fulminant hepatic failure, we found histological and immunohistochemical evidence that both human primary FLCs and HpSCs could expand and reconstitute the damaged mouse liver structures; the repopulation rate in some mice was nearly 100%.
