Figure 2From: Estrogen aggravates inflammation in Pseudomonas aeruginosa pneumonia in cystic fibrosis mice E2 treatment is correlated with an increase in inflammatory infiltrate and mucin in lung tissue sections. In lung tissue sections, E2 treated mice had (A) H&E stain: inflammatory infiltrate (arrows) and (B) PAS stain: mucin producing airway lining cells (Pink, arrows). Controls showed much less inflammatory infiltrates or mucin producing cells. Light microscopy, original magnification X 100, n = 4.Back to article page
