FGF2, or Fibroblast Growth Factor 2, is a protein that plays a crucial role in various biological processes, including cell growth, development, and tissue repair. It is part of the FGF family, which consists of several proteins that help regulate cell functions and promote angiogenesis, the formation of new blood vessels. This growth factor is particularly important in wound healing and embryonic development. FGF2 interacts with specific receptors on cell surfaces, triggering signaling pathways that encourage cell proliferation and survival. Its functions make it a key player in regenerative medicine and potential therapeutic applications.
