Stemcell, 78037.1, Human Recombinant FGF-10 (KGF-2)

Fibroblast growth factor 10 (FGF-10) is a member of the fibroblast growth factor (FGF) family predominantly expressed by mesenchymal fibroblasts during embryonic development (Emoto et al.; Igarashi et al.). It binds with high affinity to fibroblast growth factor receptor 2-IIIb (FGFR2-IIIb), and also has a weaker affinity for FGFR1-IIIb (Beer et al.). FGF-10 and FGF-7 have similar receptor binding properties and target cell specificities but are differentially regulated by components of the extracellular matrix (Emoto et al.; Igarashi et al.). FGF-10 has been shown to mediate epithelial-mesenchymal interactions, which are essential to lung development (Sekine et al; Ware & Matthay). FGF-10 also has a role in mobilization and proliferation of lung-resident mesenchymal stem cells (MSCs) and protection and repair against acute lung injury (Tong et al.; Ware & Matthay), as well as endodermal differentiation of human pluripotent stem cells to insulin-producing pancreatic-like cells (Takeuchi et al.).
