Outline of Final Research Achievements

Based on the basic science research regarding control-released platelet rich plasma, clinical protocol confirming safety and bio-formulation stability was made. This protocol including technologies such as closed-environment operation, automatic production system, efficiency of growth factor concentration check, and control-released drug delivery system. Also the protocol was submitted to Ministry of Health, Labour and Welfare as class III regenerative medical technology, and then clinical research was started. First, The radiotracer-based imaging approaches was applied to evaluate blood flow, location and vascular size of angiogenesis and arteriogenesis. Next, the effect of regenerative medicine was evaluated whom had confounding condition such as collagen disease over atherosclerosis. Control-released platelet rich plasma regenerative medicine did not cause adverse event at this point, and then clinical application is continuing.
