Abstract
The effects of a 50-Hz extremely low frequency magnetic field on cultu red K562 cells growing in suspension were studied by means of scanning electron microscopy and electron paramagnetic resonance spectroscopy. Exposure of K562 cells at 2.5 mT for periods to 96 hours induced sign ificant changes in cell-surface structure and physiology without modif ication of proliferative capability as indicated by quantitative analy sis. Thus extremely low frequency fields seem able to induce injurious , sublethal cell alterations, and the plasma membrane seems to play an important role in this effect.
