The endothelial cells of the rectal venous plexus were studied by electron microscope. The endothelial cytoplasm contained numerous specific granules, intracytoplasmic filaments, and 'anchoring filaments'. The present observations suggest that specific endothelial granules are formed in the Golgi apparatus. Thin 50-70 A and thick filaments 100-120 A were found in the endothelial cytoplasm. Also anchoring filaments between the plasma membrane of the endothelial cells and the underlying basement membrane (or subendothelial microfibrils) were present. The cytoplasmic filaments as well as the anchoring filaments are thought to be a support for the endothelial cells, functioning as a cytoskeleton.
用电子显微镜对直肠静脉丛的内皮细胞进行了研究。内皮细胞质中含有大量特异性颗粒、胞质细丝和“锚定细丝”。目前的观察结果表明，特异性内皮颗粒是在高尔基体中形成的。在内皮细胞质中发现了50 - 70埃的细丝和100 - 120埃的粗丝。在内皮细胞膜与下面的基底膜（或内皮下微原纤维）之间也存在锚定细丝。胞质细丝和锚定细丝被认为是内皮细胞的一种支撑结构，起到细胞骨架的作用。
