Cell sources for hepatocyte regeneration. Liver regeneration was suggested to result from proliferation, trans differentiation, and cell fusion, involving intrahepatic (hepatic SC, oval cells, and mature hepatocytes) and extrahepatic (BM-HSC, MSC) cell sources. BM-HSC: bone marrow derived hematopoietic stem cell, hepatic SC: hepatic stem cell, MSC: mesenchymal stem cell.
