From: Epithelial cell senescence impairs repair process and exacerbates inflammation after airway injury
Epithelial cell senescence after repeated NA exposure is accompanied by exacerbated airway inflammation. Lung tissue sections were immunostained for CD45 or CD90.2 and counterstained with hematoxylin. Arrows indicate immunopositive cells (brown). Results of quantitative analyses of the numbers of CD45-positive cells and CD90.2-positive cells in the distal airways are shown in Figure 8C.
