Figure 2.Levobupivacaine induces osteosarcoma cell apoptosis and represses invasion. (A–D) MG63 and U2OS cells were treated with levobupivacaine (2 mM). (A,B) Cell apoptosis was analyzed by Annexin V/PI apoptosis detection kit. (C,D) Cell invasion and migration were detected by transwell assays. mean ± SD, ** P < 0.01.
