Rough endoplasmic reticulum

This cluster of pancreatic cells shows basophilic RER (blue staining) at the base of each wedge-shaped cell. Only large accumulations of RER, as seen here, can be identified at the light microscopic level. Proteins synthesized on the RER are transported to the Golgi where they are packaged into secretory granules for export. These granules accumulate in the cell apex for release from the cell (exocytosis). 1000x
