Effects of acute injury with polidocanol to tracheal epithelium of Aldh2*2 Tg, Aldh2 −/− , and WT mice. a-b At 12 h after injury, most tracheal epithelial cells slough off and only a few K5+ basal cells survived. c At 48 h, these surviving basal cells are positive for PCNA. d-e At day 7, near complete repair is similarly observed in WT, Aldh2*2 Tg, and Aldh2 −/− mice. The images shown are representative images from an Aldh2 −/− mouse. n = 3–4/time point/genotype, Scale bars: 50 μm. Nuclei were stained with DAPI (blue) (b, c, e)
