GLUT9/URATv1 immunoreactivity is detected in ependymal cells of all ventricles. Frozen sections of paraformaldehyde-fixed wild-type murine brain were used for immunofluorescence staining. The red squares in the diagrams indicate the region shown in each image. a–f GLUT9 staining of coronal sections. b–d Images were obtained from the same section. Scale bar 100 µm. LV, lateral ventricle; V3V, ventral third ventricle; AQ, aqueduct; 4V, fourth ventricle
