Zusammenfassung
Clara cells are a subtype of lung epithelial cells lining the bronchioles. Their proposed function is to protect the bronchiolar epithelium by (i) secreting factors, including the Clara cell secretory protein (CCSP), (ii) detoxifying harmful substances via cytochrome P450 enzymes and (iii) acting as progenitor cell during lung regeneration after injury. To study Clara cells in vivo, several attempts have been made using a variety of CCSP transgenic and knock-in approaches. Many, if not all, of the transgenic models suffer from ectopic marker expression mainly due to xenogeneic promoter usage or random cassette i…
