| Outline of Final Research Achievements |
(Purpose) Evaluate the effectiveness of platelet rich plasma (PRP) in tissue-engineered vascularized soft tissue flaps in in-vivo chamber. (Materials and methods) Animals: Japanese white male rabbit, Chamber was used as protected space for tissue engineering, pedicle vascular bundle for vascular source, collagen sponge for scaffold of cell migration. PRP and bFGF were additionally used as growth factors and the most effective combination to get a lager and more matulated granulation tissue was evaluated. Results) Additional use of PRP prevented the white, bean-curd-like debris, which was thought to be degradation of collagen sponge as a result of foreign body reaction in the previous experiments. The combination of activated PRP and controlled release bFGF showed the most effectiveness for generation of vascularized soft tissue flaps.These results suggested the usefulness of PRP in the clinical application of in vivo tissue-engineering vascularized soft tissue flap.
