【Abstract】 Hepatic stem cells are a group of cells in liver that have the self-renewal capability and multi-differentiation potential,including oval cells,small hepatocytes and small hepatocyte-like progenitor cells.Hepatic stem cells can be differentiated into pancreastic ductal,acinar cells,intestinal epithelia cells,myocyte and even liver tumor cells under specific microenvironments.Oval cells,which were identified by cellular markers,may be derived from the embryonic stem cells and/or from the bone marrow stem cells.This paper discusses about the essence,action,origin,cellular markers,differential and potential of the hepatic stem cells,and their relationship with other cells.更多还原
