FIGURE 6. Autoradiographic images of mouse kidney slices (10 µm) obtained 30 min after injection of 5a. Images are scaled to maximal pixel intensity. (A) Transverse slice. (B) Coronal slice. (C) Same section as A after staining with hematoxylin-eosin. Kidney areas are indicated as follows: C, cortex; OS, outer stripe of outer medulla; IS, inner stripe of outer medulla; IZ, inner zone of medulla. Bar = 1 mm. (D) Autoradiographic image of mouse kidney slice (25 µm, coronal) obtained 30 min after injection of ¹¹C-methyl--D-glucoside (23).
