title: [Mitogenic action of substance P on the epithelial cells of the tongue].
abstract: Substance P (10 and 100 ng/ml) stimulates the proliferation of basal cells from rat's tongue epithelium in primary cultures with 2.5% fetal calf serum. In serum-free medium substance P have no effect on the epithelial cell growth. This neuropeptide secreted by afferent nerve fibers of the tongue epithelium is suggested to have a neurotrophic influence on epithelial cells controlling their proliferation.
