Xiaoguang Dong, assistant professor of mechanical engineering, is leading a team of researchers that has developed a system of artificial cilia capable ... an artificial trachea and sheep trachea.

The function of the trachea is to be the main passageway for air to pass from ... They are then moved up toward the mouth by cilia, where they can be coughed up or swallowed. The U-shaped sections of ...

Since mucociliary function constitutes an ... mucus glands, the cilia, ciliated cells, blood flow and the smooth muscle of the trachea. Unfortunately, there is little information concerning ...

The inside wall of the trachea has tiny hairlike structures (cilia). This keeps out tiny pieces of dust ... to build up a picture of the area on a computer screen. Lung function tests These simple ...

Transverse sections from P0 GemC1 WT/WT (upper) or GemC1 KO/KO (lower) trachea, immunostained with antibodies against keratin 5 (Krt5, basal cell marker, green) and acetylated α‐tubulin (ACT, cilia ...

The trachea is also lined with tiny hair-like structures called cilia. These help push mucus ... trachea and obstruct breathing. The primary function of the trachea is to transport air to and ...

These organoids were then carefully conditioned to form exterior-facing cilia to function as paddles for movement. Using variants of tracheal cells offered an array of anthrobot abilities ...
