The delivery of adipose-derived stem cells (ADSCs) for promoting tissue repair has become a potential new therapy, while hepatocyte growth factor (HGF) is an important growth factor with angiogenic, anti-fibrotic, and anti-inflammatory benefits. Therefore, transplantation of ADSCs into acute myocardial infarction (AMI) may improve cardiac function through angiogenesis and anti-fibrosis, and that hHGF may enhance these effects. ADSCs were isolated from human subcutaneous adipose tissue. Lentivirus vector encoding human HGF (lenti-hHGF) was constructed and infected into ADSCs. Results indicated that transplantation of ADSCs led to improvement of left ventricular function, explained partly through their ability to differentiate into endothelial cells, resulting in increased blood flow and decreased fibrosis. Furthermore, hHGF enhanced these effects. This suggests that ADSCs combined with HGF gene transfer may be a useful strategy for the treatment of patients with ischemic heart disease.
