FGF3, or Fibroblast Growth Factor 3, is a protein that plays a crucial role in cell growth, development, and tissue repair. It is part of the fibroblast growth factor family, which is involved in various biological processes, including embryonic development and wound healing. FGF3 specifically influences the growth of certain tissues and is important for the formation of the inner ear and other structures. Research has shown that FGF3 can be involved in certain diseases, including some types of cancer. Abnormal levels of this protein may disrupt normal cellular functions, leading to uncontrolled cell growth. Understanding FGF3 and its mechanisms can help in developing targeted therapies for related health conditions.
