| Outline of Final Research Achievements |
In vivo study showed that GAG content, mRNA and protein levels of decorin, biglycan，versican and condoroadherin increased in response to increased joint loading. In vitro study indicated that the mRNA levels of versican, aggrecan fibromodulin and type I collagen increased in response to stretching, while the decorin mRNA levels of lumican, decorin and tropoelastin decreased. These results indicate that mechanical stress cause complicated changes in extracellular matrix components in TMJ disc.
