cartilage rings in the walls of the trachea help to keep it open ciliated epithelium and goblet cells to clean the air before it reaches the lungs Goblet cells produce mucus which traps dust ...

The lower respiratory tract consists of the trachea, bronchi and lungs. The air passages are lined with mucous membrane composed mainly of ciliated epithelium. Cilia constantly clean the tract and ...

Specimens from 2 autopsies showed active ciliated cells thirty-six ... as well as the islands of squamous epithelium, are found. In the trachea, where carcinoma is comparatively infrequent ...

Human tracheal bronchial epithelial cells represent a heterogeneous mix of ciliated cells, basal cells, and secretory cells. When cultured at the air-liquid interface, these cells form a ...

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.

The ciliated cells ... activity in the isolated epithelial strip and in vivo 17 was greatly hampered by this factor. The method of Scudi et al., 18 employing rat tracheal rings, does not ...

Lower viral replication is associated with downregulated functional pathways in ciliated epithelial cells, rather than changes in ACE2 expression or goblet cell counts. This study identifies a ...

Characteristics that define stem cells include their capacity for self renewal, production of daughter cells and extensive proliferative capacity. In general, stem cells turn over slowly and ...
