| Outline of Final Research Achievements |
To obtain stable outcomes in regenerative medicine, quality of cells for transplantation is of great importance. Potentially, cellular stress results in the release of damage-associated molecular patterns (DAMPs), and activates immunological responses, affecting the outcomes of transplanted tissues. In this study, we intentionally prepared necrotic chondrocytes to be gradually dying and releasing DAMPs, and investigated how the viability of chondrocytes could affect the maturation of tissue-engineered cartilage. It was suggested that DAMPs from necrotic chondrocytes could prompt migration of more immune cells, worsening the maturation of tissue-engineered cartilage.
