Left panels show bright field images. () Anti-cytokeratin 13 antibody (CK13) for basal cells. () Anti-cytokeratin 18 (CK18) for ciliated cells. () Anti-mucin 5AC (MUC5AC) for secreted cells. () Antibodies against intercellular junction proteins zonula occludens-1 (ZO-1), Occludin (Occl) and E-Cadherin (E-Cad). Arrows depict staining for ZO-1 and Occludin in the intercellular junctions. Micrographs are representative of spheroids from COPD and non-COPD patients (n = 7)
