Angiogenesis
Scientists at Virginia Commonwealth University describe research in angiogenesis
April 14th, 2009
According to a study from the United States, "Glioblastoma multiforme (GBM) is one of the most highly vascularized of all human tumors. Our objective was to characterize a 3-dimensional (3-D) in vitro angiogenesis model by co-culturing HUVEC and GBM cells, and to study the role of VEGF in mediating capillary tubule formation in this model." "HUVEC-coated dextran beads were suspended in fibrin gel with human glioma cells on top. The number of sprouts and the length of the processes were measured. HUVEC can be induced to form sprouts and longer processes with lumens, in co-culture with glioma cells that secrete VEGF. Addition of exogenous VEGF enhances this effect. In the...
