A discovery about how mucus thickness is regulated could help to improve airway-clearing treatment options for people with chronic respiratory conditions such as asthma, cystic fibrosis and chronic obstructive pulmonary disease (COPD).

The team, who used single cell cloning of lung stem cells to make their discovery, is now targeting the cells for new therapeutics.
