Intracardially injected horseradish peroxidase was endocytosed by coated vesicles at the base of the RPE. The fate of these labelled vesicles was observed; they were seen to fuse either together or with cisternae of the smooth endoplasmic reticulum in the basal one-third of the RPE. Peroxidase-negative vesicles, suggesting a double population, were also observed.
心内注射的辣根过氧化物酶被视网膜色素上皮（RPE）基部的有被小泡内吞。观察了这些标记小泡的命运；发现它们彼此融合，或与RPE基部三分之一处的滑面内质网池融合。还观察到了过氧化物酶阴性小泡，提示存在双群小泡。
