Figure 5. Laser therapy in wounds resulted in (A) upregulation of growth factors and downregulation of inflammatory factors; (B) increased blood perfusion of the wound. M1-macrophage: Classically activated macrophage; FGF7: fibroblast growth factor 7; bFGF: basic fibroblast growth factor; EGF: epidermal growth factor; FDGF: fibroblast-derived growth factor; VEGFs: vascular endothelial growth factors; MMP: matrix metalloproteinase; M2-macrophage: alternatively activated macrophage; VEGF: vascular endothelial growth factor; VEGFR2: vascular endothelial growth factor receptor 2.
