Figure 3 Low concentrations of silver nanoparticles reversibly retard human dermal microvascular endothelial cells growth.
A: Human dermal microvascular endothelial cells (HMEC) were exposed to various concentrations of silver nanoparticles (Ag NP). All the samples were trypsinized and counted on the same day in which the controls reached confluence. After counting, the cells were re-seeded at the same density; B: On day 19, part of the samples were seeded in the absence of Ag NP and counted at day 31. In (A) and (B) data are expressed as the percentage of control. Data represent the means ± SD of four separate experiments. In (A) P value was calculated vs untreated cells, dP < 0.001; and in (B) P value was calculated vs cells cultured for 31 d continuously with Ag NP, aP < 0.05; C: Comet assay was performed as described on HMEC treated with Ag NP (0.5 μg/mL) for 31 d or after removal of the nanoparticles from the culture media on day 19.
