Improved Regeneration of Autologous Nerve Transplants by Means of VEGF-Gene Therapy
The impact of the Vascular Endothelial Growth Factor (VEGF) on the angiogenic cascade is proven. Recently its neuroprotective effect after peripheral nerve injuries on α-motoneurons in the spinal cord was shown. Experiments on α-motoneurons demonstrated a decreased sensitivity to ischemia under VEGF-therapy. Aim of the study was to elucidate the effect of a localized VEGF-gene-therapy using an adenoviral vector construct in the model of a peripheral nerve defect in the rat treated with an autologous nerve transplant.
Vascular Endothelial Growth Factor Gene Therapy Promotes Nerve Regeneration in a Sciatic Nerve Graft Model in Rats
: Incomplete nerve regeneration after injuries to the peripheral nervous system remains a significant problem in clinical routine and raises the need for supportive strategies. In this study we examined the effect of VEGF-gene therapy on nerve recovery after an auto-graft implantation in a 2 cm sciatic nerve defect model in 18 rats, using an adenoviral vector encoding for VEGF165 (AdCMV.VEGF 165 ) for gene transduction. Functional recovery was assessed weekly by gait analyses of the rats’ hind limbs. Morphometric evaluation including histology, axon counts, motor neuron counts and corrosion casting was carried out 18 weeks post-op. VEGF-treated animals contained a higher proportion of large…
