miR-132-3p priming enhanced the effects of MSC-EXs on decreasing ROS production and apoptosis of H/R-injured ECs via activating the PI3K/Akt/eNOS pathway. a–c Representative bands and summarized data showing the protein level of p-Akt/Akt and p-eNOS/eNOS in ECs. d, f Representative images and summarized data showing the ROS production of ECs treated by various MSC-EXs and PI3K inhibitor (LY294002), scale bar = 100 μm. e, g Representative images and summarized data showing the apoptosis of ECs treated by various MSC-EXs and PI3K inhibitor (LY294002). *p < 0.05; n = 3/group
