在蛙肠系膜毛细血管内皮小泡的电镜研究中，偶然观察到了小泡的组织结构。当单宁酸被添加到固定的组织中时，媒染剂在排除囊泡运动和保持细胞膜的不透性的条件下到达细胞质中的明显游离囊泡。这表明囊泡和细胞外部之间的空间连续性。内皮细胞中的胞质小泡显然是质膜分支、永久性或半永久性内陷的组成部分。
In EM studies of the endothelial vesicles in frog mesenteric capillaries an accidental observation was made concerning vesicular organization. When tannic acid was added to fixed tissue the mordant reached apparently free vesicles in the cytoplasm under conditions in which vesicular movement was excluded and in which the impermeability of the cell membranes was preserved. This indicates a spatial continuity between the vesicles and the cell exterior. Cytoplasmic vesicles in endothelial cells apparently are elements of branching, permanent or semipermanent invaginations of the plasmalemma.
