Abstract: | Summary An electron microscope study of the epithelium of rabbit fallopian tube demonstrated a rarely described intracytoplasmic structure consisting of an array of smooth membranes associated with glycogen particles. This organelle is seen exclusively in the ciliated cells. A three-dimensional reconstruction of these glycogen bodies has been made from serial sections. The peripheral localization of the rough-surfaced membranes in continuity with intra-corpuscular smooth membranes, which have lost their granules, suggests a possible role for the rough membranes in the genesis of the smooth membranes of these glycogen bodies. The role of both the smooth and the rough membranes in glycogenesis and glycogenolysis is discussed.This investigation was made in part in the Laboratoire d'Hormonologie et de Cytologie Expérimentale, Hôpital Broca, Paris. |
