Outline of Final Research Achievements |
Three types of disc degeneration models, which are indispensable for intervertebral disc research, have been established. Using the model that causes gradual degeneration, especially during the compression period, the notochord-derived cells disappeared early and the non-notochord-derived cells (recommending chondroid cells) relatively increased. In experiments using a dynamic loading culture device, pressure loading revealed that the involvement of a typical mechanoreceptor, integrin, is involved in disc degeneration. We made a spacer that can be inserted from the small skin in the posterior of the spine, made improvements including peripheral equipment, and confirmed by conducting large animal experiments for efficacy.

Academic Significance and Societal Importance of the Research Achievements |
腰痛性疾患は社会的に極めて重要であり、その多くは椎間板変性に由来している。しかしながらその詳細はわかっておらず、研究のための椎間板変性モデルの作成無くしては先に進めない。これらのモデルを用いて椎間板変性のKey factorを特定し、それをターゲットにした分子生物学的なアプローチにより変性椎間板の再生あるいは変性の進行抑制が可能であれば社会的意義は多大である。また、腰部脊柱管狭窄症は高齢社会におけるADL障害を呈する疾患として極めて重要であり、低侵襲手術方法の開発も極めて重要と考える。
