H-Exo promotes AQP4 polarization and reduces astrocyte proliferation in the acute phase of ICH. (A) Immunofluorescence staining of AQP4 with GFAP around hematoma foci. (B) Quantitative analysis of the percentage area of the GFAP-positive region in (A). (C) Immunofluorescence staining of AQP4 with CD31 around hematoma foci. (D) Quantitative analysis of the percentage area of double-positive areas of AQP4 versus CD31 in (B) to reflect AQP4 polarization. All data are presented as mean ± SD (n = 6 per group). p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001
