Figure 6From: Repair of tracheal epithelium by basal cells after chlorine-induced injuryMorphometric analysis of cell proliferation in tracheal epithelium after chlorine injury. Cell proliferation was assessed in EdU-stained tracheal sections as described in Materials and Methods. The graphs depict the volume density (Vv) of EdU-labeled nuclei (nEdU) relative to total nuclei in tracheal epithelium (nTotal). a, p < 0.05 vs. unexposed; b, p < 0.05 vs. proximal.Back to article page
