In this study, the brush cells were observed by transmission and scanning electron microscopy, Brush cells have been reported in various organs including the gallbladder, However, the presence of a wide intercellular space and of the basal cell under the brush cell in this organ has never been described before. The brush cells in the gallbladder were narrow at the neck portion, and had prominent microvilli at the luminal surface. They were taller and thicker than the microvilli of other cells. The bundles of filaments extended from the core of each microvillus in the apical region to the nuclear or basal region in the cell. A wide intercellular space was present between the brush cell and the adjacent cell. A basal cell lay between the brush cell and basal lamina, and they were held together by desmosomes. Therefore, it seemed that a special relationship was present between the brush cell and the basal cell. The structure of the brush cell in the mouse gallbladder resembled that of the taste cell. So it was suggested that the brush cell in the mouse gallbladder might have a receptive function.
