Rough endoplasmic reticulum

At the EM level, large accumulations of RER can be seen at the base of the cell.  The nucleus is also in the cell base, while secretory granules are in the apex, waiting release into the duct of the gland.  The segregation of the RER and secretory granules results in cell polarity, indicating the cell is making protein for exocrine secretion.  Pancreas  4000x
