Figure 3. Multiwalled carbon nanotubes (MWCNTs) inhibits tumor metastasis in SKOV3 cells. (A) The wound closure and wound healing rate of SKOV3 cells treated with different doses of MWCNTs at 0, 6, 12 h and 24 h by wound healing assay. (B) Cell migration and migration rates in SKOV3 cells treated with different doses of MWCNTs by Transwell assay. *P < 0.05, **P < 0.01, and ***P < 0.001 vs control cells.
