    Vascular endothelial growth factor (VEGF) is the most critical regulator of vascular formation. Using plasmid transfer of human complementary DNA VEGF165 (phVEGF165) we performed therapeutic angiogenesis in experimental skin and cartilage trauma in BALB/c mice. At 6 weeks of age all mice were ear-punched and phVEGF165 injected into the first ear and vector without insert or saline injection into the second one. The healing process was followed. The hollow diameter was measured and histological sections of experimental and control pinnae were taken regularly after experimental injury for hematoxylin and eosin and periodic acid Schiff staining and for human VEGF immunocytochemistry. Human VEGF expression was also checked by real-time PCR in formalin-fixed, paraffin-embedded tissue sections. Significant angiogenesis promotion and cartilage repair were observed in the mice. Administering phVEGF165 thus leads to faster cartilage regeneration even if not only on the angiogenic basis.
