Changes of morphology and E-cadherin and N-cadherin protein levels in BEAS-2B cells upon TGF-β1 and TWEAK treatment. Confluent monolayers of BEAS-2B cells were cultured for 48 h in the absence (control) or presence of TGF-β1 (10 ng/ml), TNF-α (10 ng/ml), TWEAK (100 ng/ml), or TGF-β1 in combination with TNF-α or TWEAK. E-cadherin and N-cadherin (red) was assessed by immunofluorescent staining. The nuclei were stained with DAPI for DNA (blue). Scale bar 40 μm.
