ZO-1 expression in human pulmonary diseases related to inflammation. (a) Three different tissues from normal, hyperplasia, and inflammation groups were used. Lung sections were processed with anti-ZO-1 antibody, stained with Deep-Red, and images were obtained for each core. Five separate images of each section were given a score (1– 7) by three independent scientists. (b) The expression density was used to assess stained differences between cells. *p < 0.05 compared with normal. All data shown are representative of three independent experiments.
