| Research Abstract |
Since only a very small number of nucleus pulposus cells could be obtained and their biological activity was low, it is necessary to develop a new activation method or find a new source of cells to replace the degenerated NP cells. Utilizing animal models, the data on the number of cells and the synthesis of DNA and proteoglycans showed that the nucleus pulposus cells were effectively activated by coculture system with bone marrow-derived mesenchymal stem cell having direct cell-to-cell contact. In vivo study using animal models such as beagle dog with disc degeneration also revealed to decelerate the velocity of progression of disc degeneration or regeneration. For the human application of the activated nucleus pulposus cells, an activation of human nucleus pulposus cells by human mesenchymal stem cells with coculture having direct cell-to-cell contact was also evaluated. The synthesis of DNA and proteoglycan revealed 5- fold higher than in the monolayer culture. No abnormality on the chromosome was revealed. Tumor genesis was not observed. Therefore, we concluded that the activated nucleus pulposus cells are very useful and safe for clinical application.
