TNF-α increases cleaved caspase-3 expression levels in ECFCs in a concentration- and time-dependent manner. (A) Western blot analysis of cleaved caspase-3 expression levels in ECFCs treated with TNF-α at concentrations of 10, 20 and 40 ng/ml for 24 h. (B) Western blot analysis of cleaved caspase-3 levels in ECFCs treated with TNF-α (20 ng/ml) for 12, 24 and 36 h. Values in the bar charts are presented as means ± standard deviation. *P<0.05 and **P<0.01 vs. Control. TNF-α, tumor necrosis factor-α; ECFC, endothelial colony-forming cell.
