Figure 1From: Irradiation specifically sensitises solid tumour cell lines to TRAIL mediated apoptosis Time course of induction of apoptosis in six solid tumour cell lines. Apoptosis was determined by microscopic evaluation of Hoechst stained cell nuclei 12 to 48 h after treatment with TRAIL 0,1 ng/ml and 10 Gy alone, and after simultaneous and sequential application of combined therapy. Data represent means of three independent experiments; bars ± SDBack to article page
