Fig. 4. Radiation induces apoptosis in IEC-6 cells in a time- and dose-dependent manner.

Fig. 4

IEC6 cells were treated with various doses of radiation (A) or with 6 Gy (B). Cells were collected at 24 h (A) or at various time points (B) after irradiation, stained with Annexin V-APC/propidium iodide and analyzed by flow cytometry. Shown are bar graphs of the average percent of Annexin V-positive cells vs. total cell number for each treatment with SEM from three experiments; *, P<0.05.
