Scientists Isolate Human Lung Progenitor Cells That Repair Alveolar Damage

Researchers at the University of Pennsylvania have isolated and characterized a distinct type of lung stem cell in mice and humans, which is essential for repairing lung alveoli damaged by respiratory conditions such as severe influenza. Reporting on their findings in Nature , the UPenn team suggests that the alveolar epithelial progenitor (AEP) cells could represent a starting point for developing new approaches to lung regeneration.  Their paper is entitled, “ Regeneration of the lu
