Induction of ROS generation by SWCNTs in HGFs. Cells were treated with different concentrations of nanotubes (50, 75, 100, 125, 150 μg/ml) for 24 h. The ROS production was measured by analysis of DCF fluorescence compared to untreated cultures. The results are expressed as percentage of control and reported as means ± SE of four separate experiments for each experimental point. The symbol (§) refers to the comparison between treated and untreated cultures. The symbol (*) refers to the comparison between one single dose and the previous one.
