Recombinant Human Fibroblast Growth Factor 1
Acidic FGF
Endothelial cell growth factor

FGF1 is a member of the Fibroblast Growth Factor family of proteins. Also called FGF-acidic or aFGF, FGF1 lacks signal peptides and is believed to be secreted by a nonclassical mechanism. It has been detected in large amounts in the brain and is expressed in hepatocyte cells, vascular smooth muscle cells, CNS neurons, skeletal muscle cells, fibroblasts, keratinocytes, endothelial cells, intestinal columnar epithelial cells, and pituitary basophils and acidophils. FGF1 exhibits considerable species cross-reactivity and stimulates the proliferation of cells of mesodermal origin, as well as many cells of neuroectodermal, ectodermal, and endodermal origin. It is most closely associated with FGF2 (bFGF) (see additional information).
