Mean percentage of urothelial area covered by pristine or functionalized MWCNT. Explanted mouse bladders were incubated with the various MWCNT types (0.2 mg/ml) for 1 h at room temperature using Franz diffusion cells. Subsequently, the coverage of urothelium by MWCNT was evaluated on HE-stained tissue sections by light microscopy. Results are depicted as mean ± standard error
