我们报道了大鼠唾液腺主要排泄管上皮的簇状细胞。这些细胞在唾液腺和其他器官中表现出类似的基本特征。然而，在颌下腺簇状细胞的微绒毛中存在许多膜结合的电子致密颗粒，而在其他器官中则没有。顶端细胞质含有许多囊泡，囊泡中有丝状物质，对糖缀合物起积极反应。囊泡常靠近顶质膜，似乎向管腔开放。神经末梢与突触囊泡靠近丛状细胞的基部。簇状细胞与主细胞的比例在颌下腺最高，在舌下腺最低。唾液腺簇状细胞的功能是分泌、吸收和接收。
We report the tuft cells in the main excretory duct epithelia of rat salivary glands. These cells exhibit similar fundamental characteristics in the salivary glands and in other organs. However, numerous membrane-bound electron-dense granules are present among the microvilli of the tuft cells in the submandibular gland, but not in other organs. The apical cytoplasm contains numerous vesicles with a filamentous substance that reacts positively for glycoconjugates. The vesicles frequently are close to the apical plasma membrane and seem to open into the lumen. Nerve endings with synaptic vesicles are seen close to the basal portion of the tuft cells. The ratio of the tuft cells to principal cells is highest in the submandibular gland and lowest in the sublingual gland. The functions of the tuft cells in the salivary glands are suggested to be secretion, absorption, and reception.
