We used scanning electron microscopy to study the glomerular peripolar cell in the kidneys of seven sheep. Peripolar cells were present in a variable proportion (3.6-100%) of glomeruli. Although on average two peripolar cells were present at each vascular pole, up to ten were seen on occasion. They were more often related to the afferent than to the efferent arteriole. Mapping the relative position of each cell failed to reveal any zonal distribution in the renal cortex. Scanning electron microscopy showed that they were globular in shape and had a bossellated surface. We showed by examination of cells which had been broken open that this appearance was due to the presence of cytoplasmic granules that produced bulging of the cell membrane. We suggest that scanning electron microscopy is a suitable method for studying this cell in the mammalian kidney.
我们使用扫描电子显微镜研究了7只绵羊肾脏中的肾小球极周细胞。极周细胞存在于不同比例（3.6%-100%）的肾小球中。虽然平均每个血管极有两个极周细胞，但偶尔可见多达十个。它们与入球小动脉的关系比与出球小动脉的关系更密切。绘制每个细胞的相对位置未能揭示肾皮质中的任何区域分布。扫描电子显微镜显示它们呈球形，表面有小瘤。通过检查破裂的细胞，我们发现这种外观是由于存在导致细胞膜凸起的细胞质颗粒。我们认为扫描电子显微镜是研究哺乳动物肾脏中这种细胞的合适方法。
