| Outline of Final Research Achievements |
We developed a technology to use connective tissue membranes formed around the silicone substrate under the skin of the patient by tissue engineering in vivo as a small-diameter substitute blood vessel / cardiovascular substitutes. After repeat animal experiments, we began clinical application in the field of pediatric cardiovascular surgery in 2015. We also began attempting to transplant not only autologous but also allogenic and xenogeneic tissues aiming for further application extension. We carried out various chemical treatments / decellularization treatment, evaluated the mechanical properties of the obtained tissue, and conducted an animal transplantation experiment as a pilot study.It became obvious that they function as grafts comparable to autograft . We plan to further advance research and aim for clinical application in the future.
