The fibroblast growth factor receptor (FGFR) family consists of transmembrane receptor tyrosine kinases that regulate a broad range of biological processes, including embryonic development, wound healing, and angiogenesis. Upon binding of FGFs (fibroblast growth factors) to their corresponding FGFRs, downstream signaling pathways—such as RAS-RAF-MAPK, PI3K-AKT/mTOR, STATs, and PLCγ/PKC—are activated, orchestrating cellular proliferation, survival, migration, and differentiation.
