<p>The brain sections from control and PEITC treated groups were immunostained with HER2, EGFR, VEGF antibodies and DAPI for nuclear staining after fixation, permeabilization and blocking the tumor section. The images were taken using fluorescence microscope (Olympus Inc., Center valley, PA). The expression for HER2 (Red), EGFR (Red) and VEGF (Green) was quantitated using SlideBook software (Intelligent Imaging Innovations Inc., Denver, CO, USA). DAPI was used as internal control. * P<0.05, statistically different when compared with control. Results are presented as mean ± SD of triplicates.</p
