SGC7901 cells were divided into four groups: M2-si-control-exo, M2-si-CRNDE-exo, M2-si-CRNDE-exo +PTEN inhibitor (SF1670; 50 μmol/l), M2-si-control-exo+PTEN inhibitor. All cells were treated with CDDP. The cell survival rate were measured. Data information: The results shown are from seven biological replicates.
