Biomarkers for Inflammatory Lung Disease by Patricia Silveyra

Eva Mutunga and Kate Klein. Cells lining the airways of the lung. ID Number 5763. Cells lining the airways (called the trachea) in our lungs are known as the mucociliary escalator and are our first line of defense against inhaled bacteria, allergens, pollutants and debris. Malfunctions in this system can cause or aggravate lung infections and conditions such as asthma and chronic obstructive pulmonary disease. The cells shown in gray secrete mucus, which traps inhaled particles. The colored cells sweep the mucus layer out of the lungs. This image was taken with a ZEISS ORION NanoFab microscope and shows a 10,000-fold magnification of the airway cells in mice.
