After mucus ascends the trachea, it is propelled ... with a single layer of columnar epithelial cells. The ciliated cells express approximately 200 cilia that are about 7 μm in length.

The trachea has a number of adaptations: cartilage rings in the walls of the trachea help to keep it open ciliated epithelium and goblet cells to clean ... the lungs. Cilia are small hairs which ...

indicating a potential intriguing use of adult human epithelial cells recovered from the trachea. Human bronchial epithelial cells self-construct into multicellular motile living architectures.

These cilia are linked to signaling pathways that regulate their motility, allowing epithelial tissues in airways to ... genes in samples of human airway epithelia, the cells that line the trachea and ...
