Single-chain polypeptide growth factor that plays a significant role in the process of wound healing and is a potent inducer of angiogenesis. It binds to heparin, which potentiates its biological activity and protects it from proteolysis. The growth factor is an extremely potent inducer of DNA synthesis in a variety of cell types from mesoderm and neuroectoderm lineages, and also has chemotactic and mitogenic activities. It was originally named acidic fibroblast growth factor based upon its chemical properties and to distinguish it from basic fibroblast growth factor. Other homologous FGF belonging to the same family are int-2 (FGF-3), FGF-5, FGF-6, K-FGF and KGF (keratinocyte growth factor =FGF-7 ). All factors are products of different genes, some of which are Oncogene products (FGF-3, FGF-4, FGF-5).

Recombinant Human Fibroblast Growth Factor-acidic (FGF-1) produced in E.coli is a single, non-glycosylated, polypeptide chain containing 141 amino acids and having a molecular mass of 15,967 Daltons.
