Fig. 3From: Arsenic trioxide induces apoptosis and the formation of reactive oxygen species in rat glioma cellsHOE/PI staining assay in glial (a, b), C6 glioma (c, d) and 9 L sarcoma (e, f) cells before (a, c, e) or after (b, d, f) treatment with 5 μmol/l As2O3 for 72 h. Magnification: 60×. Red arrows indicate necrosis. Yellow arrows indicate apoptosis. As2O3 might change the cell morphology of 9 L cellsBack to article page
