title: The ultrastructure of the brush cell in bovine lung.
abstract: A cell type with properties similar to those of the brush cell was recognised in the bronchial epithelium of calves. It occurred in small numbers and was not found in airways distal to the small bronchi. The ultrastructural features are described, emphasising the two constant characteristics (i) a dense population of thick apical microvilli and (ii) cytoplasmic filament bundles which extent into the microvilli.
