Overexpression of RBM10 inhibits the migration and invasion of U2OS osteosarcoma cells. (A) RBM10-overexpressed U2OS cells (RBM10) and negative control cells (NC) were seeded in Transwell chamber overnight. A cell migration assay was then performed (left) and the number of migratory cells was calculated (right). Results are shown as mean ± S.D. * P<0.05. (B) RBM10-overexpressed U2OS cells (RBM10) and negative control cells (NC) were seeded in Matrigel-coated Transwell chamber overnight. Then, a cell invasion assay was performed (left) and the number of migratory cells was assessed (right). The results are shown as mean ± S.D. * P<0.05.
