miR-21 expression level in U87-MG cells, after 24 and 48 h of co-culture with HEK-293T cells stably expressing pri-miR-21 or miR-21-sponge cells. The results revealed a potential transfer of miR-21 and miR-21-sponge from HEK-293T to U87-MG cells via conditioned media. ****P < 0.0001, which is represented by some statistical software like Graph Pad.
