Vector

A virus or plasmid (a circular, double-stranded unit of DNA that replicates within a cell independently) that harbours a DNA sequence constructed to express a specific protein into a host cell.

VEGFR-2 or Vascular Endothelial Growth Factor Receptor-2

VEGFRs are membrane receptors to which the VEGF ligand binds; VEGFR-2 is expressed on endothelial cells, and is thought to be principally responsible for angiogenesis and for the proliferation of endothelial cells. The endothelium is the thin layer of cells that lines blood and lymph vessels. The cells of the endothelium are called endothelial cells. Angiogenesis is a physiological process involving the growth of new blood vessels from pre-existing vessels.
