Flow cytometry analysis for cell cycle phases and apoptosis after 24 h of sham-exposure or intermittent exposure to the 448 kHz signal at a 50 μA/mm2 current density. a Representative images from one experimental run. Marker 1 (M1): region SubG0/G1; Marker 2 (M2): region G0/G1; Marker 3 (M3): region S; Marker 4 (M4): region G2/M. Events versus FL2-A parameter (PI fluorescence). b Percent of cells in the cell cycle phases G0/G1, S, G2/M and of apoptotic cells SubG0/G1. Data are means ± SEM of at least 3 experimental repeats, normalized over the respective sham-exposed controls. *: 0.05 > p ≥ 0.01; Student’s t-test
