Melanocyte morphology after stimulation by an extremely low frequency electromagnetic field (ELF-EMF) for 72 h. All groups were cultured in M254 media. Before ELF-EMF exposure, cells were cultured in modified M254 media containing forskolin, melanocyte-stimulating hormone (α-MSH), and 12-O-tetradecanoyl-phorbol-13-acetate for 72 h. After culturing in differentiation media, cells were treated with continuous ELF-EMFs. The α-MSH group was cultured in M254 media added to 5 nM α-MSH. (A) control; (B) α-MSH; (C) 30 Hz; (D) 50 Hz; (E) 60 Hz; and (F) 75 Hz. Original magnification was ×100; bar = 100 μm.
