| Outline of Final Research Achievements |
Our final goal of this research series is to establish the clinical therapeutic angiogenesis in patients with critical limb ischemia manifestating rest pain and/or ischemic skin ulcer due to atherosclerotic disease, Burger's disease and connective tissue diseases such as scleroderma (PSS). To this end, we have established mouse, rat and rabbit model of hind limb ischemia, and we examined the effects of the implantation of autologous adipose-tissue derived regenerative cells (ADRCs), one of the mesenchymal stem cell class, on limb blood perfusion and angiogenesis in these animal models. We also tested the effects of combination of several drugs and ADRCs, H2S on angiogenesis in hind limb ischemia model. We have already performed clinical cases using ADRC injection to patients with critical limb ischemia, and examined the possible biomarkers that can predict the salutary efficacy of this procedure. For example, we are focusing on the role of VEGF-A165b and circulating CD34+ cells.
