| Outline of Final Research Achievements |
Titanium fiber paper, which is prepared by molding titanium fibers into plates by simultaneously applying compression and shear stress at normal room temperature to retain the original fiber shape, can exhibit an elastic modulus similar to that of bone cortex and form a porous structure suitable for cell adhesion. We combined titanium fiber paper with osteoblasts differentiated from bone marrow mesenchymal stem cells and showed that the paper was better able to facilitate bone tissue repair than conventional titanium plates when implanted into rat bone defects. Also capable of being used in close contact with bone for long periods of time and promoting bone repair, titanium fiber paper has a wide range of potential applications and is expected to make great contributions to the clinical management of bone diseases, including bone fracture repair and bone regenerative medicine.
