Purity >95% as determined by SDS-PAGE. Acidic fibroblast growth factor (aFGF), also known as FGF1, is a potent inducer of DNA synthesis, cell proliferation, and has chemotactic activities. aFGF regulates cardiogenesis through protein kinase C signaling. aFGF also functions as an insulin sensitizer and mediates adipose tissue remodeling. High serum levels of aFGF are associated with type 2 diabetes mellitus (T2DM), suggesting a pathogenic role of aFGF during T2DM.
