Human Tracheal Cells are from the lining of the bronchi/trachea, the network of tubes used to convey air to the lungs. Bronchial/Tracheal cells are responsible for producing lubricating mucus to keep the airways functional and they are a type of epithelial cell, a term used generally to refer to cells lining the inside or outside of the body. These cells generate mucus and a number of other compounds, which play an important role in respiration. At Creative Bioarray, we provide 9 types of human bronchial/tracheal cells including Human Tracheal Fibroblasts, Human Small Airway Epithelial Cells, Human Bronchial Epithelial Cells (HBEpC), Lobar Bronchial Epithelial Cells, etc. These cells provide excellent model systems to study all aspects of bronchial/tracheal cells' functions and diseases, particularly those related to airway viral infections, as well as tissue repair mechanisms, signaling changes and potential treatments relevant to lung injuries, mechanical and oxidative stress, inflammation, pulmonary diseases and smoking.
