Fig. 3 NSC-Exos alleviates cerebral edema caused by cerebral ischemia-reperfusion injury. a Colocalized expression of NSC-Exos and MAP-2 positive cells in the damaged cerebral cortex. Scale bar: 20 µm. b Protein expression levels of AQP4 and its corresponding β-actin band. c Statistical map of relative expression of aquaporin-associated protein AQP4. d Water Content of brain tissue. (MAP-2, Microtubule associated protein-2; AQP4, Aquaporin protein-4;*P <0.05,**P <0.01 vs Sham group;#P <0.05,##P <0.01 vs IRI, PBS group; one-way ANOVA)
