Experimental schedule. Two weeks after Aβ injection into the bilateral hippocampus, stem cells were injected twice at intervals of 1 week. A week after last injection of stem cells, various behavior tests and immunohistochemical analyses were performed. EV study was performed on a day after first stem cell injection. Aβ: β-amyloid; MSC: mesenchymal stem cell; EV: extracellular vesicle.
