Tail-vein injection of Mim-sEVs increases autophagy flux and promotes motor function recovery. a Schematic diagram of the tail-vein injection of sEVs (200 μg). b Basso Mouse Scale Scoring for three groups at different times after spinal cord injury. Inh-sEVs: **p < 0.01; ***p < 0.001; NC-sEVs: ^#p < 0.05; ^##p < 0.01; ^###p < 0.001. c Mice was treated with NC-sEVs, Mim-sEVs and Inh-sEVs 30 min post SCI, then the expression of LC3 (green) was detected by Immunocytochemical. Scale bar: 100 µm
