[Electron microscopic study of glycogen granules in the epithelial cells of human endometrial glands].
At the early secretory stage of the menstrual cycle part of glycogen granules in the human endometrial glandular cells are limited with threelayered membranes 6--9 nm thick. Transitional forms between the above mentioned granules and vesicles derived from the Golgi cisterns were found. On moving away from the Golgi apparatus the density of these granules with the membranes disappearing, thus suggesting that the Golgi apparatus of the human endometrial glandular cells may give rise to beta-particles of glycogen, whose polysaccharid nature is confirmed by amylase digestion.
