Summary
The electron microscopical appearance of the luminal cell surface of the uterine epithelium in mouse and man was similar at similar stages of the functional activity of the epithelial cells. The inactive stage was characterized by 0.1 μ long microvilli, the stage of the sperm passage at the time of ovulation was characterized by 1 μ long microvilli, and that of the egg implantation by an irregular cell surface with several large projections.
The similarity of structural changes in the two species might imply a basic function of the cell membrane in uterine physiology. The morphological changes of the cell membrane indicate that its physical or chemical properties might be changed during the different functional states of the cell.
