The distribution of mucous cells in rat intrapulmonary airways was investigated by conventional light microscopic technique. A striking association was found between differentiation of epithelial mucous cells and accumulation of lymphoid tissue in the lamina propria of bronchioli. Nodular accumulations of lymphoid tissue, covered by a lymphoepithelium, as well as differentiation of mucous cells, increased with age. This normal development was accelerated in rats exposed to aerosolized ovalbumin.
