The Effect of Adipose-Derived Stem Cells on Full-Thickness Skin Grafts

Figure 2

Observation of blood flow perfusion. (a) Perfusion images of skin grafts at days 1, 2, 3, 7, and 14 postoperatively. The color scale of all images was analyzed by setting the lowest perfusion value to 0 and the highest perfusion value to 300. Images showed blood perfusion images in PBS group and ASCs group, respectively. (b) H&E staining at day 7 and day 14 showed the survival condition of ASC group was much better in both the wound margin and the skin grafts. Scale bar 200 μm. (The dashed area showed the wound margin. N presented normal skin, and the other side presented the skin graft.) (c) Blood flow perfusion in ASC group was higher than that in PBS group at days 3, 7, and 14. The blood perfusion was expressed as a ratio of the normal skin in the same area.
