  • Title: [Derepression of hepatocyte proliferation with changes in the functional state of the reticuloendothelial system].
    Author: Maianskiĭ DN, Shcherbakov VI.
    Journal: Biull Eksp Biol Med; 1983 Sep; 96(9):106-8. PubMed ID: 6616039.
    Abstract:
    Experiments on rats and mice were performed to study the effects of different substances modifying RES functions on hepatocyte proliferation. It was shown that as early as 24 hours after Kupffer cell (KC) overloading with colloidal iron particles the number of hepatocytes in mitosis increased. The mitotic rate increased by 32 h and decreased between 48 and 72 h following iron injection. Forty-eight h after injection of latex particles the hepatocyte mitotic peak could be identified. Twenty-four and 48 h after zymozan injection DNA synthesis in sinusoidal liver cells correspondingly increased. Hepatocytes in mitosis appeared 5 days later, reaching the peak value after 9 days followed by a decrease 12 days after zymozan injection. The depression of the hepatocyte mitotic rate was also observed 9 days after BCG and 15 days after prodigiozan injection. The data are suggestive of the importance of KC as potential inducers of hepatocyte proliferation.
