hVEGF165/hBD3 promotes wound healing in vivo. (A) Representative pictures of wound healing on day 20 after BMSC injection. The wound was almost invisible in group T, whereas it was still visible in the other three groups, especially in group S (PBS control). (B) Comparison of residual wound area between different groups (n = 6). At day 7 and thereafter, group S had the most residual wound area and group T had the least residual wound area. The order of the four groups was S > N > C > S.
