Exo‐miR‐126 enhanced angiogenesis in the wound sites of mice. (A) CD31 immunofluorescence staining of wound sections from mice receiving different treatments at day 14 post‐wounding (scale bar: 50 μm). (B) Representative images of CD34 staining of wound sections from mice receiving different treatments at day 14 post‐wounding (scale bar: 50 μm). (C) Quantitative analysis of the CD31‐positive area in (A) (n = 8). (D) Quantitative analysis of the CD34‐positive area in (B) (n = 8). *P < 0.05, **P < 0.01 vs. Control group, ^## P < 0.01 vs. Exo‐NC group. Exo‐NC, exosomes derived from BMMSCs transfected with NC‐mimic; Exo‐miR‐126, exosomes derived from microRNA‐126 overexpressing bone marrow mesenchymal stem cells
