Correlation analyses of the levels of cEPC-EXs and their carried miR-126 with the infarct volume, angiogenesis, neurogenesis and sensorimotor function of exercised mice on day 28 post-MCAO surgery. A-J, Pearson’s correlation analysis of the level of cEPC-EXs and their carried miR-126 level with the infarct volume, the number of the number of BrdU + CD31 + cells and BrdU + NeuN + cells, and left turns/10 trials and adhesive remove time in exercised mice. Data is expressed as mean ± SEM. N = 11/group.
