title: Products of activated lymphocytes stimulate Schwann cell mitosis in vitro.
abstract: Culture of Schwann cells and endoneurial fibroblasts from newborn rat sciatic nerves in the presence of supernatants obtained from concanavalin A (Con-A)-stimulated rat mononuclear cells resulted in proliferation of both cell types. Con-A did not induce Schwann cell or fibroblast proliferation. Supernatant from a Gibbon T-cell lymphoma and chromatographically purified rat interleukin-2 (IL-2) induced fibroblast but not Schwann cell proliferation, and cloned human IL-2 did not induce proliferation of either cell type. Proliferation of Schwann cells and endoneurial fibroblasts induced by activated mononuclear inflammatory cells may be important in inflammatory demyelinative neuropathies.
