Capillary density in 14-day-old wounds was determined after immunohistochemistry. Scale bar is 100 μm. (a) 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) Capillary density as the number of vWF-positive vessels per mm2 (; , CM versus UC-MSC or PBS); (; , UC-MSC versus PBS).
