Effect of PBM on the viability of MIN6 cells and rat islets. MIN6 cells and rat islets are exposed to 2.8 mW/cm² PBM illumination. a Results of a representative flow cytometry experiment on the viability of MIN6 cells after PBM. Live cells are in Q3 (annexin-negative and PI-negative). Annexin and PI conditions correspond to death control. b Effect of PBM on MIN6 cells’ viability. Results are normalized to the control value. c Representative images of islet viability experiment by confocal microscopy after PBM. Live cells are labeled with Syto13 (green) and dead cells are labeled with PI (red). d Effect of PBM on rat islets’ viability. Results are normalized to the control value. PBM: photobiomodulation, PI: propidium iodide. Results are expressed as the mean ± SEM,n = 4, Scale bares = 100 μm, One-way ANOVA Kruskal–Wallis’s test with pairwise comparison.
