[Ultrastructural analysis of the female breast alveolar ductulus cells in pre- and postmenopause].
Ultrastructural characteristics of ductular parenchyma epithelial and myoepithelial cells were analysed in 18 cases of normal female breast tissue. Different physiological states have been compared and that pre- and postmenopausal. Nuclei and cytoplasm of epithelial and myoepithelial cells have been examined and compared. There were obvious signs of secretion and that apical protein granules, "dense-core" granules and light vesicles and lipid vacuoles and glycogen granules were accumulated in the deeper parts of premenopausal breast epithelial cells cytoplasm. Morphologic equivalents of secretion and accumulated glycogen were presented in the postmenopausal breast epithelial cells. Ultrastructural morphologic characteristics of postmenopausal myoepithelial cells were not different from those in premenopausal breasts.
