New cell discovered in human lungs that may treat respiratory disease

Scientists discovered a new type of cell named respiratory airway secretory cells (RASCs) in human lungs that could help in treating chronic obstructive pulmonary disease (COPD). These cells have a regenerative ability that could replenish other cells implicated in COPD, which facilitate normal functioning of alveoli. RASCs are found in tiny airway branches near alveoli air sacs in the lungs.
