FGF, or Fibroblast Growth Factor, is a family of proteins involved in various biological processes, including cell growth, development, and tissue repair. These proteins play a crucial role in angiogenesis, the formation of new blood vessels, and are essential for wound healing and embryonic development. There are several types of FGF, each with specific functions. For example, FGF-1 and FGF-2 are known for their roles in promoting cell proliferation and survival. Dysregulation of FGF signaling can lead to various diseases, including cancer and cardiovascular disorders, highlighting its importance in maintaining healthy biological functions.
