KIF2C silencing reduces cell migration and motility in NPC. Cells were infected with lentivirus particles expressing negative control shRNA and KIF2C shRNA, and 48 h later, wound healing assay was conducted for HNE-1 (A) and CNE-1 (B) cells, respectively. Similarly, cell motilities were also monitored using a live cell imaging analyzer every 15 min for 8 h in both HNE-1 (C) and CNE-1 (D) cells. Motile trajectory of each cell for 8 h, mean total migration distances over 8 h and mean minutely migration speeds are presented.
