Assessment of Pulmonary Fibrogenic Potential of Multiwalled Carbon Nanotubes in Human Lung Cells
Figure 3
Light microscopy of nondispersed (ND) and Survanta-dispersed (SD) MWCNT-treated BEAS2B cells. BEAS-2B cells were either left untreated (a) or treated with (b) 0.2 μg/cm2 of ND-MWCNT, (c) 0.2 μg/cm2 of SD-MWCNT, or (d) 0.6 μg/cm2 of SD-MWCNT for 48 h. Large agglomerates (white arrow) were seen with ND-MWCNT (b), whereas much smaller structures of MWCNT were observed (CD). Note the interaction of cells with MWCNT which is more apparent in SD-MWCNT-treated cells.
