Exosome treatment reduced brain damage and promoted functional recovery after stroke. (A) Neurological recovery was evaluated by the modified neurological severity score (mNSS) at 1, 7, 14, 21, and 28 days post-permanent distal middle cerebral artery occlusion (pMCAO, n = 12). (B,C) Representative images of 2,3,5-triphenyltetrazolium chloride (TTC) staining in five sequential brain slices from the various groups of rats (n = 3). (D) Brain water content was evaluated at 72 h post-injury (n = 4). Data are presented as the mean ± SD. *P < 0.05, **P < 0.01, ***P < 0.001 vs. the pMCAO group. ##P < 0.01, ###P < 0.001 vs. the EXO1 (basic plasma exosomes) group.
