From: Delay of airway epithelial wound repair in COPD is associated with airflow obstruction severity
Association between the mean speed of bronchiolar and bronchial epithelial wound closure. Paired bronchial and bronchiolar epithelial cells were obtained in 12 patients and analysed in wound closure assay. Representative photographs at 0 and 18 h in a non COPD and a COPD GOLD D spirometric GOLD 3 patient (A) are presented. The association between the mean speed of wound closure of bronchiolar epithelial cells and corresponding bronchial epithelial cells is shown (B). p = 0.02.
