Figure 5

Computer-assisted phase-contrast microscopy (quantitative videomicroscopy) illustrations of human U373 glioblastoma cells treated with 10 nM hellebrigenin for 72 h. The squares on the left-handed panel of images (0 – 32 – 48 h) highlight the morphological aspects of the U373 GBM cells on the right-handed images at a higher magnification, with the appearance of marked vacuolization processes. Cells were not starved during the experiments. The images provided here are representative images obtained from triplicates in each experimental condition.
