Insulin-like growth factor 1 (IGF 1) is a single-chain polypeptide homologous to proinsulin that can be produced by a variety of cell types and acts locally through autocrine or paracrine processes. IGF 1 has both insulin-like short-term metabolic regulation and a growth factor-like long-term growth, proliferation and differentiation of a variety of cells
