The Keratinocyte Growth Factor (KGF), also known as FGF7, is a growth factor present in the epithelialization-phase of wound healing. In this phase, keratinocytes are covering the wound, forming the epithelium. KGF is a small signaling molecule that binds to fibroblast growth factor receptor 2b (FGFR2b).〔 〕 For signalling to occur, a dimer is required between two FGF:FGFR complexes that is linked together by a molecule of heparin. There are 23 known FGFs, and 4 FGF receptors. FGF:FGFR binding is complex and regulated by a variety of mechanisms in a tissue specific manner. FGF10 is also known as "Keratinocyte growth factor 2". ==See also== * Palifermin 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「keratinocyte growth factor」の詳細全文を読む スポンサード リンク
