Figure Lengend Snippet: Fig. 4. Iba-1 staining showing activated microglia/macrophage revealed that activated microglia/macrophages were significantly reduced in the exosome group (A). Measurement of IL-6 levels in brain tissue homogenates of SAH rats using ELISA revealed a significant decrease in the exosome group compared to the PBS group (B). Brain water content analysis revealed a significant decrease in the exosome group, compared to the PBS group (C). Furthermore, Evans blue extravasation was significantly reduced in the exosome group compared to the PBS group in a SAH model (D).
