Lysosomal system of Von Ebner's salivary gland in the rat

We have examined the morphology and distribution of lysosomes in Von Ebner's salivary gland utilizing TMPase as a marker. TMPase reactivity was detected basally, laterally and in the center of the cells. They include AV, Rb, MVBs and dense bodies. TL was detected for the first time in between the secretory granules and in the lateral parts of exocrine acinar cells. They were parallel to RER. In addition direct continuity between TL and MVBs and dense bodies was observed. The new locations and relations of TL support their role in pinocytotic processes and cellular regularity processes
