Endothelia of the anterior cerebral arteries in rats aged 1 to 3 days were studied. Thin (about 50-90 A) and thick (about 100-110 A) filaments are present in the endothelia. Numerous spherical- or rod-shaped bodies, measuring approximately 0.07 to 0.3 micrometer in diameter and up to 0.6 micrometer in length occur in the endothelial cells. These bodies contain a tubular structure. The diameter of the individual tubules is about 200 A. The present observations suggest that spherical- or rod-shaped inclusions are first synthesized in the rough endoplasmic reticulum and thereafter these materials are transported into the Golgi complex for maturation. A small number of the inclusions, however, may originate directly from the rough endoplasmic reticulum and not pass through the Golgi apparatus.
对1至3日龄大鼠大脑前动脉的内皮进行了研究。在内皮中存在细（约50 - 90埃）和粗（约100 - 110埃）的细丝。内皮细胞中出现大量球形或杆状小体，直径约0.07至0.3微米，长度可达0.6微米。这些小体含有管状结构。单个小管的直径约为200埃。目前的观察结果表明，球形或杆状内含物首先在粗面内质网中合成，然后这些物质被转运到高尔基体进行成熟。然而，少数内含物可能直接起源于粗面内质网，而不经过高尔基体。
