Fibroblast growth factor 1 (acidic), also known as FGF1, 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. FGF-1 is the only member of the FGF family that binds with high affinity to all four FGF receptors.1FGF1 plays an important role in hematopoietic stem cell homeostasis. The FGF pathway regulates primitive hematopoiesis by modulating transcription factors such as Gata1 expression level and activity.2
