| Outline of Final Research Achievements |
Bone tissue anisotropy is determined by the osteoblast arrangement. In bone tissue, osteoblast behaviors are regulated by the mutual activities of other types of bone cells. Understanding the cell-cell communication is essential to reveal the molecular mechanisms underlying the anisotropic bone tissue formation. A novel coculture model was established to understand the intercellular communication between osteoblast, osteoclast, and osteocyte. We discovered the mechanosensing by osteocytes regulate the osteoblast arrangement. In addition, the crosstalk between osteoclasts and osteoblasts play key roles in anisotropic bone tissue construction.
