Recent experiments performed in this same porcine model of myocardial ischemia have shown that direct intramyocardial gene transfer of naked plasmid DNA encoding VEGF (phVEGF(165), the identical plasmid used in our previous animal and human clinical trials) can be safely and successfully achieved through a minimally invasive chest wall incision.
AdGVVEGF121.10 (carrying the human vascular endothelial growth factor 121 cDNA) was administered (4 x 10(8) to 4 x 10(9.5) PU, single administration) directly to the myocardium of 11 individuals with ischemic heart disease.
We initiated a phase 1 clinical study to determine the safety and bioactivity of direct myocardial gene transfer of vascular endothelial growth factor (VEGF) as sole therapy for patients with symptomatic myocardial ischemia.
We initiated a phase 1 clinical study to determine the safety and bioactivity of direct myocardial gene transfer of vascular endothelial growth factor (VEGF) as sole therapy for patients with symptomatic myocardial ischemia.

In this brief review, the role of a prime angiogenic candidate, namely vascular endothelial growth factor (VEGF) and its homologues, in physiological and pathological angiogenesis will be discussed with particular attention to myocardial ischemia and heart failure.
Recently, the efficacy of therapeutic angiogenesis using VEGF (vascular endothelial growth factor) gene transfer has been reported in human patients with critical limb ischemia and myocardial ischemia.
Encouraging results have been obtained with the angiogenic cytokines vascular endothelial growth factor (VEGF) and basic fibroblast growth factor in animal models, leading to clinical trials in ischemic heart disease.
The results of application of vascular endothelial growth factor (VEGF) GT strategies for therapeutic angiogenesis in critical limb and myocardial ischemia in pilot clinical trials was reviewed.
The central role of vascular endothelial growth factor (VEGF) in angiogenesis in health and disease makes it attractive both as a therapeutic target for anti-angiogenic drugs and as a pro-angiogenic cytokine for the treatment of ischaemic heart disease.
Currently, about 200 patients have been treated with intramyocardial VEGF gene therapy for peripheral occlusive artery disease or for myocardial ischemia.
Therefore, with the localized induction of VEGF and the low cytotoxicity of WSLP, the pEpo-SV-VEGF/WSLP system may be helpful to eventually treat ischemic heart disease.
This review discusses proof of the concept pre-clinical studies and phase-I/II human trials using VEGF, and cellular angiogenesis at length in the light of the literature and analyzes the problems and considerations of these approaches as a treatment strategy in the clinical perspective for the treatment of ischemic heart disease.
Because hypoxia-inducible factor (HIF)-1alpha is a transcriptional activator of vascular endothelial growth factor (VEGF) and is critical for initiating angiogenic responses to hypoxia, we investigated the expression of HIF-1alpha and VEGF in specimens of human heart tissue to elucidate the molecular responses to myocardial ischemia in diabetic patients during unstable angina.
Mobilization of endothelial progenitor cells with cytokines potentiates VEGF-2 gene therapy for myocardial ischemia and enhances bone marrow cell incorporation into ischemic myocardium.
