Figure 11From: Parallel screening of FDA-approved antineoplastic drugs for identifying sensitizers of TRAIL-induced apoptosis in cancer cells Microscopy images of mitoxantrone treated PC3-TR cells. Left panels are phase contrast images and right panels are fluorescence images visualized with an annexin V and propidium iodide stain. Apoptotic cells exhibit green fluorescence only. Dead cells can exhibit either lone red fluorescence or red and green fluorescence simultaneously. Live cells are non-fluorescent. Arrows identify apoptotic cells.Back to article page
