Effect of PBM on insulin secretion of MIN6 cells and rat islets. MIN6 cells and rat islets are exposed to 2.8 mW/cm² PBM illumination. a Effect of PBM on MIN6 cells’ insulin secretion (normalized to total insulin content) in response to glucose (n = 8). Results are normalized by total insulin content. b Effects of PBM on islets’ insulin secretion (normalized to total insulin content) in response to glucose (n = 5). Results are normalized by total insulin content. c Effect of PBM on MIN6 cells’ insulin stimulation index (high glucose insulin secretion/low glucose insulin secretion)). d Effect of PBM on islets’ insulin stimulation index. PBM: Photobiomodulation. Results are expressed as mean ± SEM, One-way ANOVA Welch’s with Games Howell post-hoc test, ** p < 0.01, *** p < 0.001.
