Abstract:
:Indirect evidence for the presence of a growth inhibitor in normal human fibroblasts has been obtained previously; the inhibitory activity has been found associated with crude cell extracts, but the molecule responsible for the growth inhibition has never been isolated. We have isolated a glycopeptide fraction from human fibroblast cultures, whose synthesis decreases when the cells are stimulated into the division cycle. It was separated by electric charge, lectin affinity, and molecular mass. When added to quiescent cells simultaneously with a growth stimulus, the glycopeptide reduces DNA synthesis activity. The relationship of the kinetics of the synthesis of the glycopeptide with the cell division cycle and its molecular weight are different from what has been described so far for other growth regulators. The decreased synthesis of this inhibitor, induced by growth factors, seems to be one of the requirements for the initiation of the division cycle by human fibroblasts. This response to growth factors was stable during the lifespan of the fibroblast population and became less pronounced only in cells at the end of their replicative potential.
