Fibroblast Growth Factors (FGFs) are a family of proteins that play a crucial role in various biological processes, including cell growth, development, and tissue repair. They are involved in the formation of blood vessels, wound healing, and the development of the nervous system. FGFs bind to specific receptors on cell surfaces, triggering signaling pathways that promote cellular functions. There are several types of FGFs, each with distinct roles in the body. For example, FGF2 is important for angiogenesis, the formation of new blood vessels, while FGF1 is involved in tissue repair. Dysregulation of FGFs can lead to various diseases, including cancer and developmental disorders.
