The effects of exposure of human adipose derived stem cells to a 2.4 GHz electromagnetic field (WiFi) on cell proliferation, apoptosis and differentiation should be investigated.
Cells were divided into three groups: 1) exposure to the 2.4 GHz electromagnetic field, 2) control group incubated at 37°C, 3) control group incubated at 39°C. Two control groups were used because in a preliminary test a temperature rise of about 2°C was measured in the exposed cell culture. Thus, the 39°C control group should account for possible thermal effects.
|ばく露時間||continuous for 10 hours/day for 5 days|
|Distance between exposed object and exposure source||2 cm|
|チャンバの詳細||culture plates in a CO2 incubator|
|ばく露装置の詳細||cells were incubated under a smartphone connected to a WiFi local area network (IEEE 802.11 g); the smartphone worked actively, uploading files at 600-KB/s or 4.8 Mbps (remark EMF-Portal: contradictory specifications) speed to a laptop connected to a wireless router; temperature in incubator was maintained at 37°C and CO2 5%|
|Additional information||(remark EMF-Portal: it was not stated whether other potential EMF sources of the smartphone (e.g. GSM, Bluetooth) or MF of the incubator were deactivated during exposure)|
Cell proliferation was significantly increased in the exposure group and in the 39°C control group compared to the 37°C control group.
All other parameters did not show any significant differences between the groups.
The authors conclude that exposure of human adipose derived stem cells to a 2.4 GHz electromagnetic field (WiFi) has no effects on cell proliferation, apoptosis and differentiation apart from thermal effects.
