Rough endoplasmic reticulum

At the EM level, a large accumulation of RER can be seen surrounding the nucleus at the base of the cell. Secretory granules accumulate in the apex of the cell before being released into the duct of the gland. This spatial segregation of the RER and secretory granules is an example of cell polarity, indicating the cell is making protein for exocrine secretion.  Pancreas, 4000x
