title: Tissue culture studies of Schwann cell proliferation and differentiation.
abstract: Neonatal rat sciatic nerve Schwann cells in monolayer culture are stimulated to proliferate and to express a lipid and a protein characteristic of myelin by agents which raise intracellular cyclic adenosine 3',5'-monophosphate. Both glial growth factor and axolemmal fragments increase the rate of mitosis of cultured rat and human Schwann cells. Rat Schwann cell mitosis is enhanced by a soluble factor produced by concanavalin A-stimulated blood mononuclear cells and inhibited by lead salts. Schwann-like cells cultured from human dermal and plexiform neurofibromas resemble normal human Schwann cells in phenotype and response to mitogens.
