Effects of ZnO on apoptosis of ECFCs assessed by flow cytometry. ECFCs were exposed to ZnO-n1, ZnO-n2 nanoparticles and ZnO-micro particle at concentrations ranging from 1 to 100 μg/ml, or to ZnCl2 at the indicated concentrations for 24 h. Data are mean ± SD of four replicates. *p < 0.05 vs. control (0 μg/ml).
