A, B and C: Clonal growth and viability of BEAS-2B and SAEC cells. Figure 5A: The bar graph represents viability of BEAS-2B and SAEC cells 24 hours following exposure to MWCNT or V205. The white bar indicates viability of BEAS-2B cells. The black bar indicates viability of SAEC cells. The viability was not reduced in either the BEAS-2B or the SAEC cells. Figure 5B: The bar graph represents the viability of BEAS-2B and SAEC cells 72 hours following exposure to MWCNT. The white bar indicates the viability of BEAS-2B cells and the black bar indicates viability of SAEC cells. MWCNT exposure resulted in reduced viability in the SAEC and the BEAS-2B at 0.024, 0.24, 2.4 and 24 μg/cm2 compared to control cells. The exposure to V205 resulted in reduced viability in SAEC treated cells at all doses. *indicates statistical significance of the treated cells compared to control cells at p <0.05. Figure 5C: The bar graph demonstrates the clonal growth in BEAS-2B cells 3 weeks following MWCNT exposure and SAEC cells 4 weeks following exposure. The black bars indicate the mean number of colonies of BEAS-2B cells and the white bars indicate mean number of colonies in SAEC cells. *indicates significance at p <0.05 of treated cells compared to control cultures.
