Fig. 5From: The impact of γ-irradiation on the induction of bystander killing by genetically engineered ovarian tumor cells: implications for clinical useApoptosis measured in two human tumor cell lines using annexin V/propidium iodide. Cells were analysed with a FACSCalibur flow cytometer: a HL-60 control cell line either untreated or treated with 0.1 µM staurosporin for 4 h. b PA-STK cells unirradiated or irradiated at 100 Gy. The irradiated tumour cells were analysed 10 h after irradiationBack to article page
