[Existence of cytoplasmic bridges between gastric endocrine cells]

The fine structure of endocrine cells of the rat's stomach has been studied. 3 of 25 animals displayed structural formations, which could be interpreted as "cytoplasmatic bridges" between endocrine cells of the acid-producing part of the stomach. In these areas no plasmalemma existed between cells, and endocrine granules and vacuoles were present. There is no cytophysiological evidence of intercellular transport of such big organoids. Possible causes and conditions of formation of the above structures are discussed.
