Fig. 7From: Atomic layer deposition coating of carbon nanotubes with zinc oxide causes acute phase immune responses in human monocytes in vitro and in mice after pulmonary exposureBromodeoxyuridine (BrdU) labeled lung sections highlight airway epithelial cells undergoing DNA synthesis in treated and untreated mice. U-MWCNTs show a significant increase in the number of positively labeled cells as compared to both control and Z-MWCNT treated mice (inset panel shows BrdU positive cells indicated by arrows). The lower right hand panel shows quantitative data expressed as % positive BrdU airway epithelial cells relative to the total number of airway epithelial cells in cross-sectional profiles of small to medium-sized airways in lung sections. The number of animals per group at day one was: Control (3), U-MWCNT (4), Z-MWCNT (4). Significance is represented as *** (P < 0.001) U-MWCNTs compared to Control or Z-MWCNTs at day 1 post-exposureBack to article page
