Improved Regeneration of Autologous Nerve Transplants by Means of VEGF-Gene Therapy
2009
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.
Implication of anti-angiogenic VEGF-A165b in angiogenesis and systolic function after reperfused myocardial infarction
2020
Abstract Background Angiogenesis participates in re-establishing microcirculation after myocardial infarction (MI). Purpose In this study, we aim to further understand the role of the anti-angiogenic isoform vascular endothelial growth factor (VEGF)-A165b after MI and explore its potential as a co-adjuvant therapy to coronary reperfusion. Methods Two mice MI models were formed: 1) permanent coronary ligation (non-reperfused MI), 2) transient 45-min coronary occlusion followed by reperfusion (reperfused MI); in both models, animals underwent echocardiography before euthanasia at day 21 after MI induction. Serum and myocardial VEGF-A165b levels were determined. In both experimental MI models,…

Angiogenesis control in spine regeneration
2012
Abstract: The intervertebral disc (IVD) has a complex vascularisation pattern. While the nucleus pulposus is avascular, the annulus fibrosus as well as the endplates are vascularised. IVD degeneration is often accompanied, on the one hand, by blood vessel ingrowth into the nucleus pulposus and, on the other hand, by diminished vascularisation of the endplates. Tissue engineering of IVD, therefore, has to address the differences in the vascularisation of IVD compartments. This chapter summarises current knowledge about the mechanisms of angiogenesis and its physiological and pathological role in IVD biology. Different strategies to control angiogenesis are discussed in the chapter with examp…
