Sell S: Heterogeneity and plasticity of hepatocyte lineage cells. Hepatology. 2001 Mar;33(3):738-50.
It is hypothesized that the liver has 3 levels of cells in the hepatic lineage that respond to injury or carcinogenesis: 1) the mature hepatocyte, which responds to partial hepatectomy (PH), to centrolobular injury, such as that induced by carbon tetrachloride (CCl (4)), and to dimethylnitrosamine (DEN) hepatocarcinogenesis; 2) the ductular "bipolar" progenitor cell, which responds to centrolobular injury when the proliferation of hepatocytes is inhibited, and to N-2-acetylaminofluorene (AAF) hepatocarcinogenesis; and 3) the putative periductular stem cell, which responds to periportal injury, such as induced by allyl alcohol and to choline-deficiency models of hepatocarcinogenesis. |
