Different Cellular Response of Human Mesothelial Cell MeT-5A to Short-Term and Long-Term Multiwalled Carbon Nanotubes Exposure

Figure 1

Cytotoxicity of MWCNT in MeT-5A cells. MeT-5A cells were seeded in 96-well plate (1 × 10⁴ cells/well) and subjected to various treatments. Cell viability was determined by the LDH assay and was expressed as the percentage of the control which was without treatment. Each experiment was repeated at least three times, and error bar stands for standard deviation (SD). (a) MeT-5A cells were treated with MWCNT at different concentrations (0, 1.25, 2.5, 5, 10, 20, and 40 μg/cm²) for 24 h. (b) MeT-5A cells were treated with MWCNT for different times (0, 24, 48, and 72 h) at 10 μg/cm². versus control cells.
