Cell proliferation, mitochondrial activity, and cytotoxicity of melanocytes after 72 h exposure to extremely low frequency electromagnetic fields. (A) Cell count (to measure cell proliferation); (B) 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay (to determine cell mitochondrial activity); (C) Lactate dehydrogenase (LDH) assay (to examine cellular damage). Each bar represents mean ± standard error from independent experiments performed in triplicate (n = 5). * p < 0.05, compared to the control.
