| Outline of Final Research Achievements |
To aim for efficient bone regeneration, we employed tissue engineering which composed of mesenchymal stem cells and biomaterials. Therefore, we examined bone regeneration with bone marrow cells or adipose tissue cells/porous beta-TCP block composites by means of histological analysis. Bone marrow cells and adipose tissue cells obtained from 4-week-old GFP rat were induced into osteoblast-like cell, and then, seeded on a porous beta-TCP block. 10-week-old nude rats were implanted with the blocks in the calvariae, and then the blocks were extracted and examined histochemically. The differentiated bone marrow cells and adipose tissue cells have high osteogenic potential. Therefore, these results suggest that not only bone marrow cells but also adipose tissue cells have possibilities to be effective cell sources for bone regeneration.
