Figure 6. Cell apoptosis was detected with flow cytometry with the Annexin V-FITC/PI reagent. The fourth quadrant and the second quadrant indicated the early apoptotic cells and the late apoptotic cells, respectively. Compared to the miR-21 negative control (NC) group, the miR-21 inhibitor promoted cell apoptosis. **p<0.01, ***p<0.001.
