New Stem Cell Key To Lung Regeneration
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. Now the newly discovered lung stem cell for the mucus glands will likely yield new insights into this critical process.
The study, by scientists with the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA, represents the first time anyone has found the cell of origin for the many types of cells that make up the mucus glands and that can also repair the surface epithelium. The finding, the study states, is of “major importance to the field of lung regeneration.”
“We’re very excited that we found this population of cells because it will allow us to study mechanisms of diseases of the upper airway,” said Dr. Brigitte Gomperts, an assistant professor of pediatrics and hematology/oncology and senior author of the study. “For example, there currently are no treatments for excess mucus production, which we see in cystic fibrosis, asthma and chronic obstructive pulmonary disease (COPD). But if we can understand the mechanisms of how these stem cells repair the mucus glands, then we may be able to find a way to put the brakes on the system and prevent mucus over production.”
