Effect of exosomal miR‐133b on bladder cancer cellular phenotype. Exosomes were isolated from 5637 and T24 cells transfected with NC or miR‐133b mimics, namely NC‐EXO and miR‐133b‐EXO, respectively. Their exosomes were extracted and cocultured with BC cells for 24 hours. A CCK8 assay detection of cell viability (A). The expression of miR‐133b in 5637 and T24 cells (B). Colony formation assays for evaluation of cell proliferation (C). Flow cytometry detection of the apoptosis of 5637 and T24 cells (D). *P < .05
