RGD-Exo-circDIDO1 treatment inhibits GC cell growth while promotes apoptosis. A–E Flow cytometry analysis of cell apoptosis (A), cell growth curve (B), colony formation (C), transwell migration (D) and matrigel invasion assays (E) were performed for PBS, RGD-Exo, and RGD-Exo-circDIDO1 treated GC cells. Data are shown as mean ± SD (n = 3, **P < 0.01, *P < 0.05). Scale bars = 100 μm
