In vivo tracking of extracellular vesicles (EVs). Confocal Z-stacks collected at × 40 magnification qualitatively demonstrate that retro-orbitally injected EVs migrated through the lateral ventricle (LV) in the lateral septal nucleus (LSD, (A,B) and caudate putamen (CPu, C,D) subregions of control (A,C) and irradiated (B,D) rats. EV red; DAPI stained nuclei, blue; Scale bars: 40 µm.
