Figure 3

The wounds of mice were injected with mesenchymal stem cells derived from human umbilical cord blood (UCB group) and Warton’s Jelly (WJ group) or medium alone (Control group), and wound closure was recorded macroscopically after treatments. (a) Representative images of the gross appearance of excisional wounds over time after treatment. (b) Quantitative data concerning the proportion of the wound remaining open relative to the initial wound area at different time points after treatment. (c) Quantitative data on the visual scar area 14 days after treatment. The visual scar area was carefully circled on the images of wounds (dark dotted lines in Figure 3a). The percentage of the scar area was calculated relative to the initial wound area.
