Overexpression of MORC2 promotes migration, invasion and motility of SMMC7721 cells in vitro. (A) Cell migration was assessed using a Transwell assay in SMMC7721MORC2 and SMMC7721vector cells; the cells that migrated to the bottom surface of the filters were stained. Magnification, ×100. (B) Cell invasion was assessed using a Transwell assay with Matrigel in SMMC7721MORC2 and SMMC7721vector cells; cells, which migrated to the bottom surface of the filters, were stained. Magnification, ×100. (C) Movement ability was detected using scratch wound healing assays in SMMC7721MORC2 and SMMC7721vector cells. Magnification, ×40. Date are presented as the mean ± standard deviation of three or six independent experiments. ***P<0.001. MORC2, microrchidia; CON, control.
