Researchers at UCLA have identified a new stem cell that participates in the repair of the large airways of the lungs, which play a vital role in protecting the body from infectious agents and toxins in the environment. The airways protect the body by producing and clearing mucus from the airways. The mucus is largely produced by specialized mucus glands in the airway and the mechanisms of normal and excessive mucus production are not well understood. However, this newly discovered lung stem cell for the mucus glands will likely yield new insights into this critical process.
