The intrahepatic bile duct has been suggested to be a source of hepatic progenitor cells in the severely damaged liver. In contrast, little attention has been paid to the question of whether hepatic progenitor cells exist in the extrahepatic bile duct (EHBD). In the present study, we examined the phenotypic changes of the mouse EHBD following bile duct ligation. After bile duct ligation, the number of c-Kit-positive epithelial cells increased in the EHBD. The ligated EHBD expressed mRNA for hepatic progenitor cell markers, including c-Kit and Thy-1. Hepatocyte markers such as albumin and cytochrome P450 7a1 were also transiently detected in the EHBD after a bile duct ligation. In a culture of EHBD cells, we detected hepatic progenitor cells that were positive for both staining with anti-albumin antibodies and Dolichos biflorus agglutinin, a biliary epithelial cell-specific lectin. Furthermore, hepatic progenitor cells positive for both c-Kit and albumin were found in the cultured EHBD population. Additionally EHBD-derived hepatocyte-like cells were also observed in the culture. A transplantation study revealed that EHBD cells integrate into the parenchyma and are albumin positive. These data suggest that hepatic progenitor cells emerge in the EHBD following bile duct ligation, that subsequently give rise to hepatocyte-like cells. We also observed that the gall bladder transiently expressed hepatocyte markers after bile duct ligation. Our results suggest a potential of the EHBD and gall bladder as useful transplantable sources for liver injury.
