SEROUS ACINUS – 5
The cells of the pancreatic acini produce many different types of proteins that are secreted and conducted by the excretory duct system to the lumen of the small intestine. Many of these proteins are digestive enzymes.
In order to synthesize these proteins the pancreatic acinar cells are endowed with an abundant granular endoplasmic reticulum (ergastoplasm). It is concentrated in the basal region of each acinar cell, close to the basal lamina and stains blue-violet by a mixture of eosin and hematoxylin that will appear highlighted in dark blue in some of the cells.
The ergastoplasm surrounds partially the round nuclei located in the basal region of the cells. Some of them appear highlighted in light blue. Many contain a prominent nucleolus.
The secretion produced by the cells is accumulated in secretory grains accumulated in the apical region of the cells. This area appears highlighted in pink in several cells.
Due to the arrangement of its organelles, this type of cell is an excellent example of a polarized cell.
