Figure 2. — Pretransplant airway epithelium viability is not compromised in alcohol-fed SD donors. (A) Terminal deoxynucleotidyl transferase–mediated dUTP nick-end labeling (TUNEL) staining of pretransplant tracheal sections at 1-week ethanol diet (top panels) and 8-week ethanol diet (bottom panels). TUNEL-positive nuclei were not observed in the airway epithelium of any groups. Scale bar = 100 μm. (B) Quantification of TUNEL staining in the airway subepithelial layers. No significant differences were observed in the prevalence of TUNEL-positive cells between control (n = 4) and alcohol-fed (n = 4) donors at either 1 or 8 weeks of dietary ethanol (P > 0.05). NS = not significant.
