Cellular Effects

by Robert B. Goldberg, Ph.D., Editor

Summary

It has been suggested that magnetic field exposure alters cellular responses to chemical agents that damage DNA. To test this, one study we reviewed examined the effects of magnetic fields on cell killing by genotoxic chemicals in lymphoblastoid cell lines from normal subjects and patients with ataxia telangiectasia, whose ability to repair DNA damage is defective. A study of the effect of pulsed EMFs on growth and maturation of dorsal root ganglia nerve cell cultures was reviewed. A major motivation for this type of study lies in the great potential therapeutic advance represented of developing an effective modality for stimulating repair of damaged nerve tissue. Another study examined the effects of an extremely low frequency magnetic field on steroid synthesis by cultured human ovarian cells obtained from young women. In view of their earlier findings of elevated testosterone release in cultured mouse testicular cells exposed to similar field, the authors discussed the potential role of environmental EMF in modulating human reproductive functions.
