Effect of PBM on superoxide content and mitochondrial membrane potential of MIN6 cells. The MIN6 cells are exposed to 2.8 mW/cm² PBM illumination. a Effect of PBM on MIN6 cells’ superoxide content. Data are expressed as the mean fluorescence intensity. (n = 3 for PBM 2 h,n = 6 for PBM 24 h). b Effect of PBM on the MIN6 cells’ mitochondrial masse. c Effect of PBM on the MIN6 cells’ mitochondrial membrane potential (n = 3 for PBM 2 h,n = 5 for PBM 24 h). Data obtained by flow cytometer and expressed as the mean fluorescence intensity. The mitochondrial membrane potential is (TMRM-CCCp)/MTG. AU: Arbitrary unit; MTG: Mitotracker Green™; PBM: photobiomodulation. Results expressed as the mean ± SEM, One-way ANOVA Welch’s with Games-Howell post-hoc test, * p < 0.05, ** p < 0.01.
