Histological analysis of day-14 wounds in db/db mice. Scale bar is 100 μm. (a) H and E stained images of CM-, UC-MSC- and PBS-injected tissues from left to right, respectively (20x). (b) Magnified images of CM-, UC-MSC-, and PBS-injected tissues from left to right, respectively. (c) Wound scores at day 14 (𝑛=6; ^∗𝑃<0.05, CM versus UC-MSC or PBS); (𝑛=6; ^∗∗𝑃<0.05, UC-MSC versus PBS).
