Core Tip

Core tip: Liver regeneration capacity has been studied in different animal models of non-alcoholic steatohepatitis. This study is the first to use a high fat high cholesterol model which mimic the pathogenesis of human non-alcoholic steatohepatitis better than previous animal models. Liver regeneration capacity was evaluated using: (1) The total number of Ki-67 positive hepatocytes in the caudate lobe, evaluated in a stereology based design; (2) the regenerated protein content to describe the regenerated liver mass; and (3) the plasma concentration of coagulation factors as a marker of liver function. We found a preserved liver regeneration capacity in rats with non-alcoholic steatohepatitis, adding important knowledge to the subject.
