One of the main limitation in obtaining thick, 3-dimensional viable engineered constructs is the inability to provide a sufficient and functional blood vessel system essential for the in vitro survival and the in vivo integration of the construct. Different strategies have been proposed to simulate the ingrowth of new blood vessels into engineered tissue, such as the use of growth factors, fabrication...
Vascular endothelial growth factor (VEGF) is critical for vascularization of tissues, including tumors, making it an attractive target for controlling angiogenesis. An important first step towards the goal of effectively blocking tumor angiogenesis is to understand the relationships among tumor-promoting molecules. Whereas little is known about developmental regulation of VEGF, pathological regulation...
