Infarct-preconditioned exosomes reduced brain damage volume and neural apoptosis after stroke. A TTC-stained representative images of brain sections after middle cerebral artery embolism (MCAO). B Representative images of cranial magnetic resonance imaging (MRI) after MCAO. C Apoptotic cells labeled with Tunel emitted green fluorescence. D Quantification of the percentage of Tunel+ cells in differentiated exosomes injection after MCAO. E Quantitative analysis of infarct volume after MCAO. *P < 0.05, **P < 0.01 versus MCAO group and EXO group. Scale bars in C represent 200 μm. n = 3 in each group
