β2-microglobulin as a biomarker of pulmonary fibrosis development in COPD patients
Figure 1. HE staining of lung tissue from COPD patients. (A) Representative image of HE staining of lung tissue from COPD patients with lower serum β2M. (B) Representative image of HE staining of lung tissue from COPD patients with higher serum β2M. The right panel shows difference of alveolar wall/septum thickness in COPD patients with lower serum β2M and with higher serum β2M. P<0.05 in COPD patients with higher serum β2M versus those with lower serum β2M. Bars represent Means.
