Abstract

CXCR4 and CXCR7 chemokine receptors, and their ligands CXCL11 and CXCL12, have been often involved in tumor cell proliferation and survival. We report the expression pattern of these ligand/receptor pairs in 22 human meningiomas. High CXCR7 and CXCL12 expression was associated with high-proliferative tumors. CXCR7 levels were correlated to the content of both ligands, suggesting a possible autocrine regulation. CXCR4 and CXCL12 were homogeneously expressed within tumor cells, while CXCR7 was mainly detected in tumor endothelial cells and CXCL11 in pericytes. Our results highlight the preferential CXCR7 and CXCL12 expression within more aggressive tumors and the possible role of CXCR7 in meningioma vascularization.
