Gene expression analysis of single cell-derived clones from U-87 MG glioblastoma cell line.

<p>All RT-PCR measurements were normalized according to expression in the parental U-87 MG cell line. <b>A.</b> Thrombospondin-1 (TSP-1) relative level in U-87 MG derived clones. <b>B.</b> Expression level of genes previously shown to be upregulated in dormant tumors is shown on the left panel. Expression level of genes previously shown to be upregulated in fast-growing tumors is shown on the right panel.
