A composite supported vascular graft comprising Vascular Endothelial
Growth Factor (VEGF) and/or Platelet Derived Growth Factor (PDGF) for
enhanced site-specific angiogenesis and methods thereof are disclosed. At
least one VEGF, PDGF or angiogenesis factor is incorporated into the
composite vascular graft to facilitate enhanced angiogenesis so as the
cells are stimulated to migrate to environments having higher
concentration of growth factors and start mitosis.
