GFP staining of shCdkn2a-PDGFB-T2A-eGFP-E2A-CreERT2 GBM tumor sections shows that tumor cells are predominantly infected with the lentiviral vector. Low and high magnification (top and bottom panels, respectively) of shCdkn2a-PDGFB-T2A-eGFP-E2A-CreERT2 GBM tumor sections stained with a GFP antibody. Sections were counterstained with hematoxylin. Scale bar: 100 µm.
