To understand whether mesenchymal glioblastoma (KW10) cells express angiogenic pathway modulators, we determined expression of antagonistic pairs of angiopoietins (ANG1 and ANG2) and VEGF isoforms (VEGF-A and VEGF-B) in proneural (MTA10) and mesenchymal (KW10) cells. The gene discussed is VEGFB; the disease is glioblastoma.
