Inflammation and angiogenesis regulation effects in vivo. Tissue sections of the wound area on day 9 were utilized to examine the inflammation and angiogenesis regulation effects in vivo. (A, D, E) Double immunofluorescence staining of tissue sections of wound area for CD163 (M2 marker, red) and iNOS (M1 marker, green) (**p < 0.01, scale bar: 200 μm). (B, F, G) Double immunofluorescence staining of IL-10 (red) and IL-6 (green) (**p < 0.01, scale bar: 200 μm). (C, H, I) Double immunofluorescence staining of CD31 (red) and α-SMA (green) (**p < 0.01, *p < 0.05, scale bar: 200 μm)
