Abstract (original English)

The number of patients with ischemic cardiovascular diseases is significantly increasing as populations age. Therapeutic angiogenesis has been developed as a new treatment strategy for such patients. In recent years, the presence of mesenchymal stem cells in adipose tissues was reported, and regenerative medicine using these cells has attracted attention worldwide. In this review, we describe how the transplantation of adipose-derived regenerative cells enhances angiogenesis and tissue regeneration because of their multilineage potential and cytokine secretion. Then, the current status of therapeutic angiogenesis using adipose-derived regenerative cells in the field of cardiovascular medicine was also described. These cells present great advantages over bone marrow mononuclear cells, as these need easier, shorter, and less invasive preparations as well as less ethical concerns and immunological problems. The efficacy of adipose-derived regenerative cell transplantation in the treatment of various diseases was examined in several clinical trials with favorable results. Currently, a multicenter study of therapeutic angiogenesis using these cells is being conducted in patients with critical limb ischemia. In conclusion, we expect that this method will soon be established as a treatment for cardiovascular diseases that have been refractory to conventional treatments.
