Researchers at Center for Regenerative Medicine at Brigham and Women’s Hospital (BWH) in Boston, Massachusetts found that the human lung stem cell is self-renewing, playing an important role in regenerating tissue and may also help in the repairing of damaged lung cells. They also found that the stem cell can actually duplicate the various structures of the lung, including alveoli, bronchioles, and pulmonary vessels.
This report in this weeks New England Journal of Medicine challenges current scientific thinking about lung cells. Until this study, scientists thought there were no cells in the lung that could differentiate into the various types of lung cell.
This is just the beginning of research that is likely to lead to completely new treatments that repair and regenerate damaged lung tissue in COPD patients.
