The ultrastructure of the vestibular dark cells in the crista ampullaris of the guinea pig was observed using both transmission and scanning electron microscopy. The dark cells had numerous vacuoles of varying size and electron density, and also characteristic well-developed basal infoldings. These findings strongly suggest that the dark cells play an important role in fluid transport. Unique meshwork structures were observed on the luminal surface of the dark cells. Otoconia showing varying degree of degeneration were occasionally recognized on and near these structures. Electron microscopy revealed that the meshwork was comprised of cytoplasmic processes in a reticular arrangement. They seem to be engaged in the metabolism of otoconia, and perhaps also in fluid transport.
运用透射电子显微镜和扫描电子显微镜观察了豚鼠壶腹嵴中前庭暗细胞的超微结构。暗细胞有许多大小和电子密度各异的空泡，还有特征性的发育良好的基底褶。这些发现有力地表明暗细胞在液体运输中起重要作用。在暗细胞的管腔表面观察到独特的网状结构。在这些结构上及其附近偶尔能识别出不同程度退变的耳石。电子显微镜显示该网状结构由呈网状排列的细胞质突起组成。它们似乎参与耳石的代谢，或许还参与液体运输。
