Fibroblast Growth Factor in Diabe…erapeutic Prospects.

This review examined how fibroblast growth factor (FGF)—a family of cell signaling proteins with 23 identified subtypes—can help heal diabetic foot ulcers, which are notoriously difficult to treat. Researchers found that certain FGF types (FGF-1, FGF-2, FGF-4, FGF-7, FGF-21, and FGF-23) showed therapeutic promise when applied topically, stimulating new blood vessel formation and fibroblast growth—processes essential for wound repair.
