50 Hz ELF-EMF did not affect the growth of GC–2 cells.

<p>A. Representative images of the morphology of GC–2 cells exposed to a 50 Hz ELF-EMF at different magnetic intensities of 1 mT, 2 mT and 3 mT for 72 h. B. The 50 Hz ELF-EMF did not affect the proliferation of GC–2 cells. Cell viability was examined with the CCK–8 assay. These data are expressed as the mean ± SD of three independent experiments.
