Figure 1

Immunofluorescence of rat renal cortical sections fixed in situ on the left (a) and a paired light-transmission micrograph (t) of the same field on the right. The fluorescence images show (in red) renin in the afferent arteriole (indicated by white arrows) next to the glomerulus (G), shown at 40×. This figure depicts four examples (AD) from kidneys of rats fed a normal sodium diet. With normal sodium-diet rats, there is discrete focal localization of renin only in the juxtaglomerular apparatus abutting the glomerulus.
