Acinar cells: Cells forming the alveoli or acini of the pancreas. Pyramid-shaped cells arranged around a central lumen. Alveoli are packed close together with intervening delicate connective tissue. Cytoplasm of individual acinar cells is densely basophiiic, and the nucleus is spherical and basally located. The cytoplasmic basophilia (RNA) is a reflection of the specialization of these cells for protein synthesis and secretion of zymogen.
Centroacinar cells: Belong to the duct system. Smaller than the surrounding acinar cells. Centroacinar cells stain lighter than acinar cells and are squamous to cuboidal. Centroacinar cells occur only in the pancreas.
