Fig. 8From: Selective activation and proliferation of a quiescent stem cell population in the neuroepithelial body microenvironmentDistribution of divided (BrdU-stained; red Cy3 fluorescence) airway epithelial cells seven days after LPS challenge. Similar to the 48Â h time window, several CCSP-immunostained (blue pseudo-color of Cy5 fluorescence), BrdU-positive nuclei (arrowheads) can be observed specifically surrounding GAD67-GFP fluorescent (green) PNECs in the NEB ME. Note, however, the additional presence of CCSP-stained BrdU-labeled CCs in the surrounding airway epithelium (open arrowheads). L: airway lumen, E: airway epitheliumBack to article page
