Assessment of Pulmonary Fibrogenic Potential of Multiwalled Carbon Nanotubes in Human Lung Cells

Figure 4

Effect of Survanta-dispersed MWCNT on cell viability and proliferation. BEAS-2B cells were exposed to 0.002–0.6 μg/cm² of nondispersed (ND-MWCNT) or Survanta-dispersed MWCNT (SD-MWCNT) for 48 h. Cell viability and proliferation were determined by (a) trypan blue exclusion assay, and (b) WST-1 cell proliferation assay. Plots are mean ± S.D. from 4 independent experiments. *𝑃<0.05 versus nontreated survanta control; ^#𝑃<0.05 versus ND-MWCNT treatment.
