Abstract

The current study was designed to give transmission microscopical focus on the dark and light pancreatic acinar β-cells of young-domesticated pig (Sus Suidae). This study depends on the fresh pancreatic specimens from five healthy young pig of two months ages that collected immediately after their slaughtered at the abattoir of Abdelkader Alexandria, Egypt. In our findings, the acinar pancrease formed of pyramidal pancreatic acinar cells with large spherical nuclei of condensated heterochromatin at the periphery and prominent eccentric nucleoli. Zymogen granules observed at the apical region of the acinar cells, and they appear as electron dense bodies. Numerous mitochondria and Golgi complexes observed in the acinar cell cytoplasm. The electron dense acinar cells were joined by junctional Complexes. The rough endoplasmic reticulum was more prominent in the electron-dense acinar cells than did electron-lucent acinar cells. There was no connective tissue capsule separate the acinar portion of pancrease from the pancreatic islets. The pancreatic islets mainly formed of Beta cells. The irregular α-cells possess numerous small granules. The cytoplasmic B-cells granules were surrounded by hallow area and enclosed by a limiting membrane. Delta cells were generally polygonal in shape and found in clumps throughout the islet and they were also identified in between β-cells. Their granules were of moderate electron density and were generally smaller than β-cells’ granules. The limiting membrane was tightly enclosed the delta cells granules and the hallow area around the granule were found similar to the granules of β-cells.
