"Primary" cilia were present in the endothelial cells of human aortic fatty dots and streaks but not in those of normal intima. They had the features of cilia of the "9 + 0" axonemal configuration observed in many other cells. A lateral foot process and transitional fibers "anchored" the ciliary basal body in the cytoplasm, but rootlets were not identified in material examine. Ladder-like configurations interconnected the two centrioles (= diplosome) of control endothelium. The "primary" cilia of endothelium differed from those of the rudimentary type observed in smooth muscle cells in similar lesions of man, but shared many features with cilia of those present in experimental atherosclerosis in rabbit. Cilia were rarely described in vascular endothelium. It is believed that, to date, they were not reported to occur in normal or pathological arteries in man. It is being stressed that whereas the significance of these unusual organelles remains uncertain, their widespread occurrence may indicate that their role is more important than was believed previously, and they should cease being a curiosity only.
“原发性”纤毛存在于人类主动脉脂肪斑和条纹的内皮细胞中，而正常内膜的内皮细胞中则没有。它们具有在许多其他细胞中观察到的“9 + 0”轴丝结构的纤毛特征。一个外侧足突和过渡纤维将纤毛基体“锚定”在细胞质中，但在所检查的材料中未发现根丝。梯状结构连接了对照内皮的两个中心粒（=二联体）。内皮细胞的“原发性”纤毛与在人类类似病变的平滑肌细胞中观察到的原始类型的纤毛不同，但与兔实验性动脉粥样硬化中存在的纤毛有许多共同特征。血管内皮中很少描述有纤毛。据信，迄今为止，尚未报道它们在人类正常或病理动脉中出现。需要强调的是，尽管这些不寻常细胞器的意义仍不确定，但它们的广泛存在可能表明它们的作用比以前认为的更为重要，而且它们不应仅仅被视为一种奇闻。
