Peritoneal mast cells were easily identified by the presence of a cytoplasm dominated by distinctive secretory granules
which stain metachromatically (Fig.
Rapid ATP-dependent priming of secretory granules
Proteoglycan 1, secretory granule
(PRG1), an early response gene regulated by P53 and NF-[kappa]B (Schafer et al.
Electron density of the secretory granule
was low, and the internal space of the secretory granule
was filled with fine granular substances.
Few light and moderate electron dense secretory granules
were located close to the lumen.
The secretory granules
were always in the basal cytoplasm.
28] Anderson at al detected that in DM induced rats macroscopic salivary glands, a great amounts of clustered of lipid droplets especially in serous acinus and reported that it could be caused by intake of lipid into the cells for using as a resource of energy or reduction in secretory granules
or in plasma membrane materials.
The NS cells are the largest cells, and their cytoplasm contains densely packed and strongly stained secretory granules
Moreover, some moderate electron-dense secretory granules
(30-60 nm in diameter) and scanty cisternae of the rough endoplasmic reticulum (RER) were observed.
The aim of this paper is (1) to identify secretory granules
in the tube ultrastructure of P.
bound to the end of an actin filament can move to the plasma membrane as a result of the contraction of acto-myosin that is activated by [Ca.
Rarely, cells contained multiple, eosinophilic, round, 2-3[micro]m diameter secretory granules
