The viability of HAECs incubated with DMSA-Fe2O3. Data are expressed as mean ± SD from independent experiments. Control values from HAECs incubated without DMSA-Fe2O3 were defined as 1. (a) HAECs were incubated with DMEM containing the gradient concentrations of DMSA-Fe2O3 for 24 h (0.001, 0.01, 0.02, 0.05, 0.1, 0.2 mg/ml), n = 7. (b) HAECs were incubated with DMEM containing 0.05 mg/ml DMSA-Fe2O3 for the indicated time (4, 24, 48, 72 h). n = 5. *p < 0.05 vs. control; **p < 0.01 vs. control.
