“…As an essential vascular growth factor, bFGF plays a significant role in wound healing, including stimulating fibroblast growth and proliferation, regulating collagen metabolism, stimulating endothelial cell division, and triggering vascular regeneration. 18 VEGF is a mitogenic stimulating factor and chemokine for endothelial cells, stimulating endothelial cell growth and displaying synergistic effects with bFGF to promote wound vascularization for wound repair. 19 On day 3, the expressions of bFGF and VEGF in FG-SVF-3 were significantly higher than in control, gauze, and FG groups.…”
