Fibroblast Growth Factor-10 (also called KGF-2) is a heparin binding growth factor that stimulates the proliferation and activation of cells that express FGF receptors. FGF-10 is mostly related to FGF-7/KGF and is expressed during development and preferentially in adult lungs. The human FGF-10 is a 19.3 kDa protein containing 170 amino acid residues.
