[Characteristics of liver regeneration and growth in 3-week-old mice of different strains].
Three-week mice of C57BL strain are characterized by low proliferative activity of hepatocytes during normal growth of the liver. Hepatocytes of mice of this strain also had low proliferative activity 44 hours after partial hepatectomy (16%). Mice of the same age, but of other strains (mongrel, CBA, CC57BR) had higher mitotic indices both during normal growth and during regeneration (42; 70 and 60%, respectively). This peculiarity in the mitotic activity of hepatocytes of mice of different strains was also present 7 days after the beginning of the experiment. The data obtained indicated the genetic determination of the level of proliferative activity of hepatocytes.
