The average healing time and percentage of wound healing in each group. The average healing time of Conc. Hypo-AMSCs-CM group (10 rats) is 16.2 ± 0.98 days, Hypo-AMSCs-CM group (10 rats) is 17.7 ± 0.78 days, and the control group (10 rats) is 21.3 ± 1.10 days (a). There was significant difference between the Conc. Hypo-AMSCs-CM and Hypo-AMSCs-CM groups (P = 0.002) and between Hypo-AMSCs-CM and control groups (P < 0.001). Percentage of wound healing of groups on 7, 14, and 21 days after surgery (b). The Conc. Hypo-AMSCs-CM treatment improved wound healing compared with the Hypo-AMSCs-CM at 7 (P < 0.001) and 14 (P < 0.001) days (Figures 2(b) and 3(b)). The Hypo-AMSCs-CM group's wound healing was also significantly different from that of the control group at 7 (P < 0.001), 14 (P < 0.001), and 21 days (P = 0.0005) (Figures 2(b) and 3(b)) too.
