S2 , n = 3). Each cell culture was performed at 37 °C in an atmosphere containing 5% CO 2 , and treated with various concentrations of drugs for 48 h. Cell viability was assessed using the MTS assay reagent (Promega). Data were analyzed using a nonlinear regression curve-fitting package in Prism 4 (GraphPad Software Inc.) (Fig.
S2 ). The drugs tested included: docetaxel, a mitotic inhibitor; irinotecan, a topoisomerase I inhibitor; 5-fluorouracil (5-FU), a thymidylate synthase inhibitor; sunitinib, a multi-receptor tyrosine kinase (RTK) inhibitor; tirapazamine, a hypoxia-activated prodrug; and FX11, a lactate dehydrogenase inhibitor. Radial organization of each cell on the spheroidal culture dish (IWAKI) conferred resistance to the most of drugs tested." width="100%" height="100%">
