Figure 5From: Irradiation specifically sensitises solid tumour cell lines to TRAIL mediated apoptosis Microscopic evaluation of normal tissue cells. Lack of apoptosis was determined by microscopic evaluation of Hoechst stained cell nuclei. Micrographs depict cells of eight different normal tissues, 48 h after irradiation alone and after sequential treatment with 10 Gy 12 h previously to application of 1,0 ng/ml TRAIL.Back to article page
