Figure 1.

Effect of RES on the viability of EPCs treated with TNF-α as determined using an EdU assay. Images from five random fields per well were captured at ×200 magnification. Treatment with TNF-α decreased the proliferation of EPCs, which was restored by co-culture with TNF-α and RES. EPCs treated with DMSO only served as the blank group. Data are presented as the mean + standard error of the mean, n=5. **P<0.01, as indicated. RES, resveratrol; EPCs, endothelial progenitor cells; TNF-α, tumor necrosis factor-α; EdU, 5-ethynyl-2′-deoxyuridine; DMSO, dimethyl sulfoxide.
