Overexpression of miR-124 inhibits osteosarcoma cell migration and invasion.

<p>(A) MG-63 and U2OS cells were not transfected or transfected with 50 nmol/L of miR-10b mimics or sramble or inhibitor for 24 hours, and wounds were made. The relative ratio of wound closure per field is shown. (B) (C) MG-63 and U2OS cells were not transfected or transfected with 50 nmol/L of miR-10b mimics or sramble or inhibitor for 24 hours, and migration (B) or transwell invasion (C) assay was performed. The relative ratio of invasive cells per field is shown. Magnification for identification of migration is ×400 and invasion ×40. All data is shown as mean±SD. *p<0.05, **p<0.01 and ***p<0.001.
