AA2G-treated BMSCs promoted wound healing in mice. a Overview of size changes of the wound made in the back skin of mice among the three groups at day 0, 3, 7, and 14 post-treatment. Bar = 5 mm. b The rate of wound closure after BMSCs or AA2G-treated BMSCs engrafting into the wounds (n = 3). P < 0.05 based on one-way ANOVA. c HE staining of wound granulation tissue in control, BMSCs, and AA2G-treated BMSCs groups at day 3, 7, and 14 post-wounding. The double-headed black arrows indicated the edges of the scars. Bar = 500 µm. d Masson staining of repaired tissue at day 3, 7, and 14 in control, BMSCs, and AA2G-treated BMSCs groups. Bar = 500 µm
