[The three-dimensional ultrastructure of the pancreatic acinar cell (authors transl)].

The pancreatic acinar cells of normal rats were studied by scanning electron microscope. A three-dimensional image is presented of the structure and arrangement of the zymogen granules as well as of the apical microvilli and the zymogen discharge in the pancreatic acinar cell. The study of these structures in physiologic and pathologic conditions by scanning electron microscopy can be recommended to support the understanding of findings obtained by light and transmission electron microscopy.
