Fig. 2From: Arsenic trioxide induces apoptosis and the formation of reactive oxygen species in rat glioma cellsThe annexin V-FITC/PI assay for apoptotic and necrotic cells. Cells were stained with annexin V-FITC and PI, and analyzed using a FACSScan flow cytometer. a C6 cells were treated with 5 μmol/l As2O3 for 24, 48 and 72 h. The apoptotic rate was 5.57, 12.01 and 14.35%, respectively. b 9 L cells were treated with 5 μmol/l As2O3 for 24, 48 and 72 h. The apoptotic rate was 2.12, 5.92 and 13.13%, respectively. c Glial cells were treated with 5 μmol/l As2O3 for 72 h. The apoptotic rate was 3.59%. d The quantification data. *p < 0.05 vs. glial cellsBack to article page
