Outline of Final Research Achievements

In the present study, we analyzed expression profiles of spinal components, including annulus fibrosus, nucleus pulposus, paraspinal ligaments, etc. by lasermicrodissection and RNA sequencing. We performed pathway analyses and identified TGF-beta signaling may play pivotal roles in develpment of spine. We further identified candidate genes expressed in the inner layer of annulus fibrosus, and developed their Cre mice.

Academic Significance and Societal Importance of the Research Achievements

変形性腰椎症は変形性膝関節症を上回る膨大な患者数がいるものの、人工膝関節置換術のような長期に安定した治療法はない。分子病態解明、さらには発生学的研究においても、脊椎は四肢関節と比べて大きく立ち遅れている。本研究によって得られた組織特異的Creマウスなどのバイオリソースや発現解析のデータベースは、脊椎疾患の研究に広く貢献するものである。
