Figure 5. Effect of exosomal-miR-1228 derived from BM-MSCs on growth and apoptosis of gastric cancer cells. (A) miR-1228 was lowly expressed in gastric cancer cells. (B) Expression of miR-1228 in gastric cancer cells transfected with miR-1228-mimics, miR-1228-inhibit, miR-NC after co-culture with exosomes. (C) After co-culture, the cells transfected with miR-1228-mimics had a slower proliferation, while those transfected with miR-1228-inhibit had an accelerated proliferation. (D) As shown by EdU cell proliferation assay, the proliferation of cells transfected miR-1228-mimics was accelerated, while that of transfected miR-1228-inhibit was slowed down. (E) After co-culture, the cells transfected with miR-1228-mimics had an accelerated apoptosis, while those transfected with miR-1228-inhibit had a decreased apoptosis. ^aP< 0.05 vs. miR-NC, ^bP< 0.01 vs. miR-NC.
