Histological analysis of the skin after H&E staining. (a) A schematic of a transverse section is depicted for proper identification of the respective regions. (b, c) Images of granulation tissue were obtained from the healing wound. Three days after wounding, the HUVEC-CM group showed greater inflammatory cell infiltration than did the other two groups. The epithelial cell migration distance seven days after wounding is the distance between the black lines. (d) Measurement and analysis of the length of new epithelial tissue ().
