Outline of Final Research Achievements

We investigated that the state without mechanical stress due to developmental dislocation of hip affects joint morphogenesis histologically and immunohistochemically through analysis of hip dislocation model rats. Furthermore, a mechanical stress response genes were identified in gene expression analysis. These results suggest that the genes involved in chondrogenesis and maintenance may be reduced due to the absence of appropriate mechanical stress, which may result in joint degeneration.
