Figure 3From: Homozygous deletion of TNFRSF4, TP73, PPAP2B and DPYD at 1p and PDCD5 at 19q identified by multiplex ligation-dependent probe amplification (MLPA) analysis in pediatric anaplastic glioma with questionable oligodendroglial component Tumor immunoreactivity. (A) GFAP immunoreactivity was variable whereas Synaptophysin was negative. (B) Cytoplasmic immunoreactivity for Vimentin and CD57 (HNK-1) were positive. (C) Nuclear p53 was positive in 15%-20% of cells. (D) Growth fraction (ki 67) was approximately 30%.Back to article page
