Effects of BK preconditioning on capillary tube formation and vascular endothelial growth factor (VEGF) levels in cultured hEPCs. A. Representative photographs of the tube formation of Matrigel-coated cultured hEPCs in various groups (original magnification: 100 ×). B. Quantitative analysis of the mean tube length, which was measured by using Image-Pro Plus and was calculated against control groups. C. Enzyme-linked immunosorbent assay of VEGF levels in culture media. All values are expressed as mean ± SEM. (n = 5 for each group; *P < 0.01 versus other groups).
