Effects of nsPEFs on MSC apoptosis and viability. a Fold changes of live cells by flow cytometry of Annexin V-FITC/PI double stained cell, compared with the control group (non-pulsed samples). n = 4. b Cell count as quantified by Kit-8 assay at day 1. n = 4 for each group. Cell count was expressed as fold of control (non-pulsed samples). *, P < 0.05; **, P < 0.01; ***, P < 0.001
