Fibroblast Growth Factor 9 （FGF-9） is a member of the fibroblast growth factor family that plays a critical role in various biological processes, including embryonic development, tissue repair, and cell proliferation. FGF-9 is involved in the regulation of cell growth, differentiation, and survival, particularly in the development of the skeletal, nervous, and reproductive systems.
In rats, FGF-9 is essential for normal development and function of various tissues and organs. It exerts its effects by binding to specific cell surface receptors and activating downstream signaling pathways that control cellular responses.
