FGF-10, also named keratinocyte growth factor 2 (KGF-2), is a member of the fibroblast growth factor (FGF) family and is functionally similar to the other FGF family member FGF-7. FGF-10 acts as a paracrine growth factor and plays an important role in embryonic development, cell growth, and cell differentiation. During embryonic stages, FGF-10 is essential for lung development, promoting lung morphogenesis, branching, and airway extension. FGF-10 was revealed to participate in wound healing, promoting growth of epithelial cells in normal and wounded tissue. Increased expression of FGF-10 and the receptor FGFR2-IIIb has been reported to associate with various malignant diseases, such as prostate, breast, pancreas, and colorectum cancer, suggesting the role of FGF-10 in carcinogenesis.
