Effects of cyclic stretch on NO production from rat AF cells. a The effect of cyclic stretch on NO production of rat AF cells for different duration in the supernatant (n = 5). *P < 0.05 vs. control, **P < 0.01 vs. control. b The effect of cyclic stretch on iNOS mRNA expression of rat AF cells for different duration (n = 5). **P < 0.01 vs. control. c Fluorescence staining for NO. NO-positive cells (green) obviously increased in the cells subjected to cyclic stretch for 24 and 36 h than that in static control (0 h)
