Figure 7From: Repair of tracheal epithelium by basal cells after chlorine-induced injuryCell proliferation and K5 expression in middle trachea after chlorine injury. Mice were exposed to chlorine and injected with EdU 17 hr prior to euthanasia and collection of tracheas. Tracheal sections were stained for EdU (green) and K5 (red), and nuclei were labeled with DAPI (blue). Scale bar in Panel E represents 40 μm for all panels.Back to article page
