The posterior-superior portion of the membranous wall of the chinchilla saccule is lined by pigmented epithelial cells which contain golden brown granules having three components (lipid droplets, granular matrix, and dense globules). Histochemical and electronmicroscopic studies indicate that the dense component is a form of melanin. The pigmented cells show morphological features suggestive of fluid transport function; they are also involved in decalcification and phagocytosis of otoconial crystals. These findings provide evidence that the saccular wall epithelium plays an active role in regulating endolymph composition and in clearance of debris from the endolymphatic space.
毛丝鼠球囊膜壁的后上部分由色素上皮细胞排列，这些细胞含有具有三种成分（脂滴、颗粒状基质和致密小球）的金棕色颗粒。组织化学和电子显微镜研究表明，致密成分是黑色素的一种形式。色素细胞显示出提示液体运输功能的形态特征；它们还参与耳石晶体的脱钙和吞噬作用。这些发现提供了证据，表明球囊壁上皮在调节内淋巴成分和清除内淋巴间隙中的碎片方面发挥着积极作用。
