Measurement of invasion and migration of SaOS2 cells. (A) Invading and migrating cells were stained with 0.2% crystal violet and visualized by microscopy. (magnification 100 ×). (B) Invasion and migration assay indicated LV-COX-2siRNA-1 significantly decreased the invasion or migration ability of the SaOS2 cells. Data are presented as mean ± s.e.m. # P < 0.001, compared with LV-Control and parental SaOS2 cell group.
