Immunostaining of angiogenic markers
3mm punch biopsy (RazorMed) will be obtained from the wound edge at multiple timepoints. The samples will be processed for paraffin embedding and 7μm serial thin sections will be cut. Markers for angiogenesis (CD31, alpha-SMA) and cell proliferation (Ki-67) antibodies will be used for immunostaining on the paraffin section according to the previously published protocol. The positively stained cell numbers in the DFU zone in each patient will be quantified using imaging software according to published protocol. The paired T test will be adopted to compare the difference of MSCs proportion, angiogenesis, and cell proliferation in each patient by SPSS 18.0 software for windows (SPSS, Chicago, IL, USA). Nonparametric test will be used for comparison of mean values with p<0.05 considered as statistically significant.
