Scanning electron microscopy of the lining of the pituitary cleft was carried out in normal, lactating, castrated, adrenalectomized, and cyproterone-treated adult rats. Four cell types could be differentiated in the posterior wall in control and experimental animals: (1) cells with a smooth surface, (2) cells with microvilli located at the cellular borders, (3) ciliated cells, and (4) cells with evenly distributed microvilli. The anterior wall showed mainly cells with few microvilli located at their margins, and clusters of ciliated cells. In normal, and more frequently in experimental animals, the anterior wall showed shriveled cells, and variously sized cavities. Colloid appeared either as a network of finely granular material or as compact bodies adhering to the epithelial surface. These observations suggest that a compact component of the colloid is derived at least in part from degraded cells.
对正常、泌乳、去势、肾上腺切除及经醋酸环丙孕酮处理的成年大鼠垂体裂衬里进行了扫描电子显微镜检查。在对照和实验动物的后壁可区分出四种细胞类型：（1）表面光滑的细胞；（2）细胞边界处有微绒毛的细胞；（3）纤毛细胞；（4）微绒毛均匀分布的细胞。前壁主要显示边缘有少量微绒毛的细胞以及纤毛细胞簇。在正常动物中，尤其是在实验动物中，前壁出现皱缩细胞和大小各异的腔隙。胶体呈现为细颗粒物质的网络或附着于上皮表面的致密体。这些观察结果表明，胶体的致密成分至少部分源自降解的细胞。
