FGF-4 (Fibroblast Growth Factor-4), also known as FGF-K and K-FGF, is a secreted angiogenic factor that is mitogenic for fibroblasts and endothelial cells. The protein encoded by this gene is a member of the fibroblast growth factor (FGF) family. FGF family members possess broad mitogenic and cell survival activities and are involved in a variety of biological processes including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion. During development, it is required for maintenance of the trophoectoderm and primitive endoderm, and it cooperates with FGF-8 in the apical ectodermal ridge. FGF-4 promotes embryonic stem cell proliferation and may also aid stem cell differentiation.
