The genotoxic effects of exposure of mouse neuronal cells to a 60 Hz magnetic field should be investigated.
In previous studies by the authors, the genotoxic effects of extremely low frequency magnetic fields in several epithelial and fibroblast cell lines had been investigated (Lee et al. 2012, Jin et al. 2014, Jin et al. 2012, Jin et al. 2015, Yoon et al. 2014). With this article, the study series has been expanded by research on neuronal cells.
Mouse hippocampus neuronal cells were divided into two groups: exposure to the magnetic field and sham exposure.
A positive control was performed. All results were obtained from at least three replicate experiments.
|ばく露時間||continuous for 4, 6, 12, 16 or 24 hours|
|チャンバの詳細||exposure chamber in CO2 incubator|
|ばく露装置の詳細||cells in 100 mm cell culture dishes were placed in the exposure chamber inside the incubator; the exposure chamber was equipped with coils and was shielded; during exposure, the temperature in the chamber was maintained at 37 ± 0.3°C by circulating water and the temperature of the culture medium was monitored at 2-hour intervals; the incubator had a humidified atmosphere of 95% air and 5% CO2|
|Sham exposure||A sham exposure was conducted.|
|Additional information||sham exposed cells were treated in another incubator under the same experimental procedures with the exception of ELF-MF exposure|
After 6 hours of exposure, cell numbers were significantly higher in the exposure group compared to the sham exposure group. All other parameters did not show any significant differences at any time point between exposed and sham exposed cells.
The authors conclude that exposure of mouse neuronal cells to a 60 Hz magnetic field has no genotoxic effects. In synopsis with the previous studies, they see a varying sensitivity of different cell lines to genotoxic effects.
