From: Delay of airway epithelial wound repair in COPD is associated with airflow obstruction severity
Cell proliferation during epithelial wound closure in non COPD and COPD patients. Representative photographs (x10 enlargement) of Ki-67 and DAPI staining, as well as merge images in non COPD and COPD bronchial epithelial cells after 18 h of repair (A). Quantification of the number of Ki-67 positive cells expressed as a percentage of total cell number at 0 h, 6 h, 12 h and 18 h of repair (B).
