Figure 6From: Radioresistance of human glioma spheroids and expression of HSP70, p53 and EGFrMO59J human GBM spheroids proliferation after treatment with 5Gy irradiation, (a) PD098059 (50 μM), (b) wortmannin (5 μM), alone or in combination. Volume of spheroids was 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
