Figure 2. Ropivacaine decreases invasion and migration of breast cancer cells. (A–D) The MCF-7 and MDA-MB-231 cells were treated with ropivacaine (1 mmol/L) or equal volume saline. (A and B) The cell migration and invasion were examined by transwell assays in the cells. (C and D) The migration and invasion were measured by wound healing assays in the cells. The wound healing proportion was shown. N = 3, The independent experiments were repeated for three times. Data are presented as mean ± SD. Statistic significant differences were indicated: *P < 0.05, **P < 0.01.
