Angiogenesis is essential for tumor growth and relies on the production of angiogenic factors. By comparative analysis using RT-PCR method of angiogenic growth factors: VEGF, bFGF, PDGF-A, angiogenin- 1 and IL-8 we established the level of expression of these genes necessary for angiogenesis in glioma and neuroblastoma cell lines. Our analyses were also extended to CD44 gene, which plays an important role in cascade of metastasis and progression of brain tumors. Significant differences in the level of gene expression of angiogenic factors and CD44 gene between the two cell lines observed throughout this study can be used as a prognostic marker for predicting clinical outcome in human brain tumors at the time of the initial staging.
