To analyze expression of endoglin on single-cell level, we performed single-cell real-time polymerase chain reaction (scRT-PCR) in cells from six freshly dissociated human glioblastoma tissues using CD31 and \documentclass[12pt]{minimal}\usepackage{amsmath}\usepackage{wasysym}\usepackage{amsfonts}\usepackage{amssymb}\usepackage{amsbsy}\usepackage{mathrsfs}\usepackage{upgreek}\setlength{\oddsidemargin}{-69pt}\begin{document}$$\alpha$$\end{document}αSMA as markers of endothelial cells and pericytes/VSMC, respectively. This evidence concerns the gene ENG and glioblastoma.
