Quantitative ultrastructure analysis of neuroendocrine cells of gastric mucosa in normal and pathological conditions

Figure 1 G cell of the antrum containing both vesicular and compact granules with a floccular content.

Figure 2 D cell granules are usually rounded, homogeneous, of low electron density and with closely applied membranes.

Figure 3 EC cell granules appear to be pleomorphic, such as being oblong, ovoid, round, etc. , with high density.

Figure 4 ECL cells show the characteristic of vesicular-type granules and thin haloed granules with an irregular argyrophilic core eccentrically located in wide space.

Figure 5 Electron micrograph of contiguous gastric glands shows cross sections belonging to different endocrine cells.
