[Retracted] Study on the Mechanism of Action of STAT3 in the Drug Resistance of Gastric Cancer Cells

Figure 6

Apoptosis of each group. (a–i) Flow cytometry apoptotic quadrant diagram. (j) Statistical graph of apoptosis rate.  < 0.05, DDP STAT3(-) group vs. negative control group. Note: A means negative control; B means FITC negative control; C means PI negative control; D,E, and F means the DDP group, G,H, and I was the DDP STAT3(-) group. Q1: annexin V-FITC-/PI+; the cells in this area are necrotic cells. There may also be a few late apoptotic cells; Q2: annexin V + FITC+/PI+; the cells in this area were late apoptotic cells; Q3: annexin V-FITC+/PI-; the cells in this area were early apoptotic cells; Q4: annexin V-FITC-/PI−; the cells in this area were living cells.
