Sstem cells responsible for lung-tissue regeneration

A study in the journal Nature sheds light on the mechanism behind lung regeneration with the discovery of adult lung stem cells p63+/Krt5+ in distal airways of mice infected with the H1N1 virus. Jackson Laboratory researchers found that when grown in culture, they form alveolar-like structures and migrate to inflammation sites following infection. When the cells were removed, the subjects failed to recover from infection, which caused scarring and impaired oxygen exchange.
