Fibroblast Growth Factor 4 (FGF-4) is a growth factor predominantly expressed during embryonic development, playing a key role in limb development. In culture, FGF-4 has been shown to be an important growth factor for fibroblasts and endothelial cells. Human FGF-4 shares high homology and cross-reactivity with the mouse protein. Recombinant human FGF-4, produced in E.coli, is a non-glycosylated protein containing 177 amino acids and having a total molecular mass of 19 kDa.
