Regeneration of neuronal fibers and blood vessels. Immunofluorescence staining of the NF-200⁺ neuronal fibers (a) and vWF⁺ blood vessels (b) in the peri-infarct cortex of each group at day 14 after MCAO. Scale bar = 50 μm. Analysis of the integrated optical density of NF-200⁺ neuronal fibers (c) and number of vWF⁺ blood vessels (per mm²) (d) in each group. **p < 0.01, compared with the Sham group; ^## p < 0.01, compared with the MCAO + ADSC group. ADSC adipose-derived stem cell, MCAO middle cerebral artery occlusion, NF-200 neurofilament 200, vWF von Willebrand factor
