Angiogenesis
New angiogenesis findings from University of California described
July 8th, 2008
"Pleiotrophin (PTN) is produced under ischemic conditions and has been shown to induce angiogenesis in vivo. We studied whether or not PTN exerts chemotaxis of pro-angiogenic early endothelial progenitor cells (EPCs), a population of circulating cells that have been reported to participate in and stimulate angiogenesis," scientists in the United States report. "Chemotaxis of EPCs, isolated from blood of healthy humans (n = 5), was measured in transwell assays. PTN at 10-500 ng/ml elicited dose-dependent chemotaxis of both EPCs and human umbilical vein endothelial cells (HUVECs), but not of human coronary artery smooth muscle cells (CASMCs) and T98G glioblastoma cells...
