[Histophysiological modifications of the amnion in the rat at the end of gestation].
Amniotic epithelium of the rat has been studied during the eight last days of pregnancy, by scanning electron microscope analysis. The cells of this organ progressively become larger and flatter. Changes on their surface have also been observed : density of microvilli increases but single cilia disappear. These changes are related to modifications in the exchange processes.
