Fibroblast growth factor 8 (FGF8), also known as AIGF and HBGF-8, belongs to the FGF family. FGF family members possess broad mitogenic and cell survival activities, and are involved in a variety of biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion (PMID: 11276432; 15863033). FGF8 stimulates growth in an autocrine manner in normal individuals but mediates hormonal action during tumorigenesis (PMID 17512240). Defects in FGF8 cause Kallmann syndrome type 6 (KAL6) and idiopathic hypogonadotropic hypogonadism (IHH) (PMID 18596921).
