Exosomal miR-15a and miR-92a inhibited migration and invasion of glioma cells. The effects of exosomal miR-15a on a transverse migration, and c vertical migration and invasion in T98 and U251 cells and the effects of exosomal miR-92a on b transverse migration, and d vertical migration and invasion in T98 and U251 cells as analyzed by scratch wound healing and transwell assays, respectively. Error bars denote standard deviation of triplicates. ***P < 0.001; **P < 0.01; *P < 0.05. Original magnification ×40 for scratch wound healing assays and transwell assays
