Stimulation of the Proliferation of Mesenchymal Stem Cells from the Femur of Wistar Rats by Nanosecond Microwave Radiation: Dependence on the Number of Pulses.

The effect of nanosecond repetitive pulsed microwave radiation (RPMR) (50–4000 pulses, pulse repetition rate of 13 Hz, peak power flux density (pPFD) of 140 W/cm2, and carrier frequency of 10 GHz) on the stimulation of proliferation of mesenchymal stem cells (MSCs) is investigated. The effect of exposure was assessed by the change in the number of cells in the culture after a single irradiation with different numbers of pulses. The effect was the most pronounced after exposure with 100 and 50 pulses; the maximum rate of the effect realization is in 24 h. [ABSTRACT FROM AUTHOR]
