Figure 2From: O6-methylguanine-DNA methyltransferase is downregulated in transformed astrocyte cells: implications for anti-glioma therapiesHistological features of s.c. xenografts derived from the transformed NHA cells. Formalin-fixed paraffin-embedded tissue sections (5-μm-thick) of xenografts derived from NHA/TSR (left) and NHA/TSRA (right) cells were subjected to histological analyses. Low- (top) and high- (middle) magnification images (H&E staining; scale bar, 200 μm) and immunohistochemistry using an anti-Ki-67 antibody (bottom) are shown.Back to article page
