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.
通过扫描电子显微镜分析，对大鼠妊娠最后八天的羊膜上皮进行了研究。该器官的细胞逐渐变得更大更扁平。其表面的变化也被观察到：微绒毛密度增加但单根纤毛消失。这些变化与交换过程的改变有关。
