Figure 2: Distribution of BrdU-positive cells. Boxplot illustrating the numbers of BrdU cells counted in the airway tissues, separated by compartment, area of interest and time points. Overall cell counts were significantly greater for the mucosal versus submucosal ( ) compartments and for the damaged and transitional relative to the undamaged areas of interest. There was an increase in the numbers of BrdU-positive cells at day 3 post injury as compared to the naïve (time point 0) ( ). Upper and lower box plot margins represent the interquartile range; middle bar indicates the median. The points outside the ends of the whiskers are outliers. The graph was plotted based on the absolute number of cells stained with BrdU on each area measured. Arrows show BrdU-positive cells.
