This is an in vitro study investigating whether the RF EMFs from smartphones can cause harm to human tissues. Adipose-derived stem cells (ASCs) were incubated under a smartphone connected to a Wi-Fi network, which was uploading files for 10 hours a day, for a total of 5 days. Two groups of control cells were incubated under a temperature of 37°C and 39°C, respectively. It was found that the cell proliferation rate was higher in Wi-Fi-exposed cells and 39°C control cells compared with 37°C control cells, which the authors point out may be attributable to the thermal effects of Wi-Fi exposure. Other analyses showed no remarkable differences among the 3 groups. The authors conclude that there are no harmful effects from a smartphone’s Wi‑Fi exposure to human ASCs.
