对某些蛋白质分泌细胞中高尔基体区域与其他细胞内细胞器关系的电子显微镜观察证实并扩展了现有的假说。在几种细胞类型的显微照片中，核旁高尔基体区域被观察到与核“孔”密切相关。胃浆质膜的“过渡元素”具有“气泡”，这可能代表了一种促进脑池内内容物进入高尔基带的运输过程。这种性质的“起泡”过程可能是高尔基体小泡的一个来源。观察到不同密度的酶原颗粒，并推测其意义。可见淡淡的高尔基体空泡。据推测，这些液泡是从这些细胞类型的分泌产物中分离出来的相对液体物质的堆积。对这些来自推理证据的假设进行了讨论和推广。
Electron microscopical observations on the relationship of the Golgi region to other intracellular organelles in certain protein-secreting cells have substantiated and extended existing hypotheses. In micrographs of several cell types, the juxtanuclear Golgi regions were observed to be closely associated with nuclear "pores." The "transition elements" of the ergastoplasmic membranes possess "blebs" which may represent a transport process facilitating the movement of intracisternal contents into the Golgi zone. A "blebbing" process of this nature may be one source of the small variety of Golgi vesicles. Zymogen granules of different densities were observed and their significance was postulated. Light Golgi vacuoles were observed. It is suggested that these vacuoles represent accumulations of relatively fluid material segregated from the secretory product in these cell types. These hypotheses from inferential evidence are discussed and extended.
