Objectives This study investigated the efficacy of human skeletal myoblasts (SkM) mediated either human vascular endothelial growth factor-165 (hVEGF165) or angiopoietin-1 (Ang-1) on vascular development and myocardial regional perfusion. Methods A porcine heart model of chronic infarction was created in 28 female swine by coronary artery ligation. The animals were randomized into: (1) group-1, DMEM injected (n=6), (2) group-2, Ad-null transduced SkM transplanted (n=6), (3) group-3, Ad-hVEGF165 transduced SkM transplanted (n=8), and (4) group-4, Ad-Ang-1 transduced SkM (n=8). Three weeks later, 5 ml DMEM containing 3×108 SkM carrying exogenous genes were intramyocardially injected into 20 sites in left ventricle in groups-2, -3 and -4. Animals in group-1 were injected 5 ml DMEM without cells. Animals were kept on 5 mg/kg cyclosporine per day for 6 weeks. Regional blood flow was measured using fluorescent microspheres. The heart was explanted at 2, 6 and 12 weeks after transplantation for histological studies. Results Histological examination showed survival of lac-z expressing myoblasts in host tissue. Capillary density based on Von Willebrand factor-VIII (vWF-VIII) at low power field (×100) was 57.13±11.85 in group-3 at 6 weeks and declined to 32.1±5.21 at 12 weeks, while it was 39.9±10.26 at 6 weeks and increased to 45.14±6.54 at 12 weeks in group-4. The mature blood vessel index was highest in group- 4 at 6 and 12 weeks after transplantation. The regional blood flow in the center and peri-infarct area was significantly increased in animals of groups-3 and -4. Conclusions SkM carrying either hVEGF165 or Ang-1 induced neovascularization with increased blood flow. Ang-1 overexpression resulted in mature and stable blood vessel formation and may be a more potent arteriogenic inducer for neovascularization.

This article reviews the scientific development of angiomyogenesis using VEGF165-myoblasts, a patented biotechnology platform in regenerative medicine associated with Human Myoblast Genome Therapy (HMGT), also known as Myoblast Transfer Therapy (MTT). VEGF165-myoblasts are the leading biologics for angiomyogenesis. This review also compares the safety and efficacy of VEGF165-myoblasts transduced using adenoviral vectors, nanoparticles or liposomes, in anticipation of their application in clinical trials in the near future. VEGF165-myoblasts are differentiated myogenic cells capable of extensive division, natural cell fusion, nucleus transfer, cell therapy and genome therapy. Following transplantation they survive, develop and function to revitalize degenerative myocardium in heart failure and ischemic cardiomyopathy animal studies. VEGF165-myoblasts are second generation products of HMGT/MTT which replenishes live cells and genetically repairs degenerating myofibers in Type II diabetes, muscular dystrophies, aging dysfunction and disfigurement. Myoblasts have also been used to enhance skin and muscle appearance in cosmetology. We envision that VEGF165-myoblasts will provide better outcome than their non-tranduced counterparts. Myoblasts are not stem cells. Their competitive advantages over stem cells are presented.

Glucagon-like peptide-1 receptor agonists favorably address all components of metabolic syndrome

Cardiovascular death is the leading cause of mortality for patients with type 2 diabetes mellitus. The etiologyof cardiovascular disease in diabetes may be divided into hyperglycemia per se and factors operating through components of metabolic syndrome(Met S). Hyperglycemia causes direct injury to vascular endothelium and possibly on cardiac myocytes. Met S is a cluster of risk factors like obesity, hyperglycemia, hypertension and dyslipidemia. The incidence of this syndrome is rising globally. Glucagon-like peptide-1 receptor agonists(GLP-1RA) are a group of drugs, which address all components of this syndrome favorably. Experimental evidence suggests that they have favorable actions on myocardium as well. Several compounds belonging to GLP-1RA class are in market now and a large number awaiting their entry. Although, originally this class of drugs emerged as a treatment for type 2 diabetes mellitus, more recent data generated revealed beneficial effects on multiple metabolic parameters. We have studied literature published between 2000 and 2016 to look into effects of GLP-1RA on components of Met S. Results from recently concluded clinical trials suggest that some of the molecules in this class may have favorable effects on cardiovascular outcome.
