Effects of Sinusoidal Electromagnetic Field on Structure and Function of Different Kinds of Cell Lines

Abstract: This study investigated that whether a 2 mT, 60 Hz, sinusoidal electromagnetic field (EMF) alters the structure and function of cells. This research compared the effects of EMF on four kinds of cell lines: hFOB 1.19 (fetal osteoblast), T/G HA-VSMC (aortic vascular smooth muscle cell), RPMI 7666 (B lymphoblast), and HCN-2 (cortical neuronal cell). Over 14 days, cells were exposed to EMF for 1, 3, or 6 hours per day (hrs/d). The results pointed to a cell type-specific reaction to EMF exposure. In addition, the c… Show more

“…Purkinje cell morphological changes may also be caused by decreased nuclear activities leading to reducing of cellular activities. These findings also reinforce other studies such as Sul et al (2006) and also Manti and Darco (2010). In the study Sul et al (2006), 2 mT EMF was induced into several cell types of cortical neurons, in vascular smooth muscle cells of aorta, fetal osteoblasts and limphoblast B.…”

The study proves that EMF can manipulate cell proliferation and reduce the recovery of DNA.…”

“…For instance, significantly increased growth rate and decreased proinflammatory chemokine production have been described on human keratinocytes (HaCaT) exposed to 50 Hz, 1 mT MF [59]. Other authors have described alterations in the kinetics of the cell cycle and/or in its regulatory proteins, under exposure to ELF fields [4,60,61]. Also, Ke et al [62] reported EGF-receptor clustering and Ras activation in Chinese hamster lung fibroblasts exposed to 400 μT MF.…”

“…Sul et al [61] reported that 3 h/day exposure to a 60 Hz, 2 mT MF stimulates proliferation in the lymphoblastic cell line RPMI 7666, but inhibits proliferation in muscle cells T/G HA-VSCM. By contrast, pulse wave, 16 -80 Hz MF at 1.55 mT did not affect significantly proliferation in HepG2 [63].This specificity in the cellular response could explain in part the inhomogeneity in results reported by different authors using different exposure conditions or different in vitro models, as proposed by Ross [64] or Zhang et al [65].…”
