| Outline of Final Research Achievements |
To investigate the mechanism of mechanical stress-induced inhibition of chondrogenic differentiation, we applied the mechanical tensile force to micromass cell culture from mouse embryonic limb bud or mandibular condylar cartilage (MCC). Mechanical stretching enhanced the expression of Caspase-3, and repressed the expression of Caveolin-1, Galectin-3, Patched in MCC micromass culture by antibody array analysis. Immunohistochemical analysis showed up-regulation of Caveolin-1, Galectin-3 and Patched during MCC development. These results indicate that Caveolin-1, Galectin-3 and Patched are associated specifically with as mechanical response of cartilage differentiation in MCC.
