In vitro effect of a glycopeptide acting in vivo on hepatocyte cell cycle

Abstract
A factor specifically inhibiting the hepatocyte cell cycle in vivo was found to block the G1-S transition of liver cells in vitro. It proved to be non-toxic in our culture conditions, as judged by the reversibility of the effect on cell proliferation. It was not active on DNA synthesis in fibroblastic cell lines (3T3).
