Vascular endothelial growth factor production and regulation in rodent and human pituitary tumor cells in vitro [PDF]

, 2001
Angiogenesis, the formation of a new blood supply, is an essential step in tumorigenesis. Although vascular endothelial growth factor (VEGF) is known to be a very potent angiogenic factor in most solid tumors, little is known about its production and ...
