Analysis of the relationship between AAV-5HRE-bFGF-DPSCs and vascular endothelial cells. (A) Immunofluorescence staining showing the expression of N-cadherin (green), bFGF (red) and CD31 (purple) in the Sham, SCI group, AAV-5HRE-DPSCs (CON-DPSCs) group and AAV-5HRE-bFGF-DPSCs (bFGF-DPSCs) group at day 30. The nucleus is labeled by DAPI (blue). Magnification: 20X; Scale: 100 μm. (B–C) Comparison of the fluorescence intensity of N-cadherin and CD31 of positive cells (relative to SCI group). (D–G) The ratio of different cells in the Sham, SCI group, AAV-5HRE-DPSCs (CON-DPSCs) group and AAV-5HRE-bFGF-DPSCs (bFGF-DPSCs) group. * represents P < 0.05. ** represents P < 0.01. *** represents P < 0.001. n.s. represents no statistical significance. Data are represented as mean ± SD (n = 6). (For interpretation of the references to colour in this figure legend, the reader is referred to the Web version of this article.)
