Figure 5. Immunohistochemistry for AQP4, AQP9, and GFAP at the crushed site on day 7.

Figure 5

Representative photographs from 3 independent samples are presented. A. Some GFAP-positive cells still exist at the crushed site (arrowheads), where immunoreactivity to AQP4 is almost completely lost indicating the presence of AQP4-negative astrocytes (arrows) at the crushed site. Bar  = 100 µm. B. Immunoreactivity to AQP9 is intensified at the crushed site (arrowheads) where immunoreactivity to AQP4 is clearly reduced. Bar  = 100 µm.
