Figure 1From: Radioresistance of human glioma spheroids and expression of HSP70, p53 and EGFrEffects of irradiation on UGBM1 (a), U-87MG (b) and MO59J (c) human GBM spheroids proliferation. Volume of non-irradiated or irradiated (5, 10 or 20 Gy) spheroids were determined every 3 days during a period of 15 days by measuring the spheroids diameter. Data was plotted as the mean ± SD of 24 GBM spheroids of three different experiments.Back to article page
