Paracrine signaling

Paracrine signaling is a form of cell signaling, a type of cellular communication in which a cell produces a signal to induce changes in nearby cells, altering the behavior of those cells. Signaling molecules known as paracrine factors diffuse over a relatively short distance (local action). The highly conserved receptors and pathways can be organized into four major families based on similar structures: fibroblast growth factor (FGF) family, Hedgehog family, Wnt family, and TGF-β superfamily. Fibroblast growth factor and Fibroblast growth factor receptor (FGFR). FGFR belongs to Receptor tyrosine kinases, class V. Hedgehog signaling pathway TGF beta signaling pathway‎ Wnt signaling pathway
