FGF1 and bacterial infectious disease: An injectable hydrogel encapsulating acidic fibroblast growth factor (aFGF) and phage had significant bacteriostatic activity against MDR Escherichia coli (E. coli), and significantly increased the VEGF, α-SMA and collagen I expression levels in regenerated tissues at day 7, indicating that hydrogels containing aFGF can effectively improve tissue regeneration, enhance angiogenic activity, promote skin regeneration and prevent bacterial infections (Zhang et al., 2020).
