Abstract:
:A current concern about the biological effects of electromagnetic fields (EMF) is increasing with the wide spread use of X-band microwaves (MW, 8-10 GHz range). Gigahertz transverse electromagnetic (GTEM) field flat transmission lines are currently being used for experimental exposure of biological samples to high frequency EMF. Experiments carried out on human cells in culture require optimal growing temperature conditions, i.e. 37 °C, 5% CO2 in a humidified atmosphere. The aim of our work has been: i) to built up an original incubator set-up, the so called GTEM-incubator, for exposure of human cells in culture to MW inside a GTEM-chamber, under optimal growing physical conditions; ii) to make the validation of the GTEM-incubator by growing cell samples inside the non-energized GTEM-chamber (test sample) comparing the results with the ones obtained from cell samples grown inside a standard incubator (control samples). The features for comparison were: cell morphology, expression and distribution of cytoskeleton proteins, genotoxicity, viability and cell cycle progression. Any variation in any of the studied parameters would allow for detecting any possible failure or misconception in our GTEM-incubator working test. The results obtained in control and test incubators showed non-significant differences in the development of both cell populations for any of the studied parameters. Thereby our GTEM-incubator is considered valid for our purposes of human cell exposures to X-band MW.
