Jan 1, 2018
This animal study examined pulsed-wave 2.45 GHz microwave radiation exposure (1 or 3 hours daily for 3 weeks) in adult and juvenile rats and assessed neurogenesis-related markers in the rostral migratory stream. The authors report reduced cell proliferation in adults and longer-lasting effects on cell death after…

This in vitro study tested several complex low-intensity, low-frequency EMF patterns on proliferation of B16-BL6 mouse melanoma cells. A specific pattern (Thomas-EMF) with a 3 ms point duration reportedly inhibited proliferation and increased calcium uptake, while other timing settings did not. The authors conclude…
RF-EMF exposure at 1800 MHz did not elicit DNA damage or abnormal cellular behaviors in different neurogenic cells.

Jan 1, 2017
This in vitro study assessed whether intermittent 1800 MHz RF-EMF exposure induces DNA damage or alters cellular behavior in three neurogenic cell lines. Cells were exposed at an average SAR of 4.0 W/kg for 1, 6, or 24 hours and evaluated for γH2AX foci, cell cycle progression, proliferation, and viability. The…

This in vitro study tested 50 Hz, 3 mT electromagnetic field (EMF) exposure and 808 nm low-level laser (LLL), alone and combined, on human adipose tissue-derived mesenchymal stem cells from six donors. The authors report increased cell numbers after 7 days with EMF, greater increases with LLL, and the largest…

Jan 1, 2017
This in vitro study examined how 50 Hz low-frequency EMF and a nitric oxide donor (Deta-NO) affect stemness and neuronal differentiation markers in rat bone marrow mesenchymal stem cells. The authors report that high NO (1 mM) combined with EMF reduced stemness markers and increased neuronal differentiation markers,…

Jan 1, 2016
This in-vitro study examined whether 50 Hz extremely low frequency electromagnetic fields affect proliferation in HeLa and CHO cell cultures. The abstract reports increased proliferation in exposed cells versus controls, with the largest reported increase under repetitive exposure at 2.49 mT (40 minutes every 12…

Jan 1, 2015
This in vitro study exposed BEAS-2B human bronchial epithelial cells to a 1.8-GHz continuous EMF at SAR 1.0 W/kg and assessed wound-healing related endpoints. EMF exposure decreased cell migration in a scratch assay compared with controls. The authors report no cytotoxicity, no inhibition of proliferation, and no…

Jan 1, 2012
This in vitro study exposed newborn rat calvarial osteoblasts to a 3.9 mT static magnetic field for varying durations (0–4 hours). The authors report increased cell proliferation and markers of osteoblast differentiation and mineralization versus control, including higher ALP activity, calcium content, and…
Influences of electric field on living cells in a charged water-in-oil droplet under electrophoretic actuation.

Jan 1, 2011
This experimental study examined whether strong electric fields used for electrophoretic actuation of charged water-in-oil droplets affect living cells inside the droplets. Using Trypan blue and cell growth tests across electric field strengths of 1–3 kV/cm and varying actuation times, the authors report no…

Jan 1, 2011
This in vitro study exposed newborn rat calvarial osteoblasts to 50 Hz sinusoidal electromagnetic fields at 1.8 mT for different daily exposure times (0.5–3.0 h). The authors report inhibited osteoblast proliferation at longer exposure times, alongside increased differentiation markers (ALP activity) and…
