Outline of Final Research Achievements |
Autologous cartilage tissue transplantation for tissue deformities in the craniofacial region is fraught with problems such as the highly invasive nature of cartilage harvesting and quantitative limitations. Although there are growing expectations for regenerative therapy using human chondrocytes as a new treatment method, it has not been possible to reconstitute cartilage tissue that can be transplanted intact in vitro. Although it has been possible to reconstitute cartilage tissue without using scaffolds in vitro using a low-speed rotational suspension culture technique, the technique is still somewhat immature histologically. To solve this problem, we attempted to reconstitute mature cartilage tissue in vitro using a high-speed rotational culture technique. As a result, a variety of mature cartilage tissues were reconstituted, ranging from films to masses.
