Representative immunoistochemical images of E-cadherin and vimentin in lungs. Representative immunoistochemical images of E-cadherin and vimentin in lung sections from mice exposed at 30 days to MWCNTs through pharyngeal aspiration. E-cadherin was mainly expressed in type II pneumocytes in both control and MWCNT exposed lungs. The number of E-cadherin positive cells in NP-exposed compared to control sections was decreased (a, c, e), while the expression for vimentin was increased (b, d, f) (20×; scale bar = 60 μm)
