Cyclic changes in the fine structure of the epithelial cells of human endometrium
Abstract
PIP: Endometrial biopsies from the corpus uteri of women of reproductive age with normal 28-day cycles were processed for electron microscopy in order to examine the refinements of ultrastructure which occur as part of the cyclic hormonal input. The description of the structure of epithelial cells includes: 1) the endoplasmic reticulum and ribosomes, 2) mitochondria, 3) the nucleus, 4) the golgi complex and secretory bodies, 5) lysosomes, 6) annulate lamellae, 7) luminal surface, 8) basal surface, 9) lateral surface, and 10) the nucleolar channel system. The variations in glycogen synthesis during the cycle are presented, as well as uterine secretions. The effects of estrogen and progesterone on the epithelial cells are described.
