Representative microscope images of BEAS-2B cells. Cells were incubated for 96 h in either the absence (CTRL) or presence of different concentrations (5.5, 11, 22 and 44 μg/ml) of pMWCNT (a-b) or MWCNTg (c-d). After the incubation, the cells were rinsed with PBS and observed by optical microscopy (a-c) or fixed with paraformaldehyde and fluorescently labelled as described in Methods (b-d). a-c Representative images are shown (10×; scale bar = 50 μm). b-d Actin filaments were visualized in red, nuclei in blue. Representative images are shown (63×; scale bar = 10 μm)
