Bronchioles of the distal conducting airway are lined by a simple epithelium composed primarily of nonciliated secretory (Clara) cells and ciliated cells. These cells are long-lived in the normal lung; renewal is mediated by cells that constitute a nonclassical stem cell hierarchy. Within this type of hierarchy, facultative progenitor cells are responsible for normal epithelial maintenance and rare adult tissue-specific stem cells are activated only in response to depletion of the facultative… CONTINUE READING
