title: Multiple rough endoplasmic cisternae in "C" cells.
abstract: Multiple rough endoplasmic cisternae were found in "C" cells of the adult rat, at interphase. They are considered to be normal constituents of "C" cells. Their morphological relation to rough endoplasmic reticulum and their close proximity to mitochondria, Golgi dictyosomes and secretory granules suggest that they may have a role in the secretory activity of this endocrine cells.
