Dose-dependent cytotoxic activity of AgNPs (a); and the induced morphology injury of SMMC-7721 cells (b). (a) LS174T, A549, MCF-7 and SMMC-7721 cells were incubated with 0, 10, 20, 30, 40 and 50 μg/mL AgNPs, 10% (v/v) callus extracts as well as 0.79 ppm AgNO₃. * p < 0.01 vs. control. HL-7702 and SMMC-7721 cells were incubated with 0, 25, 50, 75, 100 and 125 μg/mL AgNPs. * p < 0.01 vs. HL-7702. Data presented are the means ± SD of results from three independent experiments. (c) Cells were treated without (1); and with 10 (2); 20 (3); 30 (4); 40 (5); and 50 (6) μg/mL AgNPs.
