| Outline of Final Research Achievements |
Altered function of the intervertebral disc leads to various degenerative spine disorders. We established an isolation method for retrieving purely annulus fibrosus cells from intervertebral disc of C57BL/6 mouse. We then tested whether CD146, a marker for mesenchymal stem cells in various organs, relates to proliferation and differentiation of annulus fibrosis cell. We isolated AF tissue from mouse and cultured isolated cells to analyze their cell surface markers and multi-potency. Result showed that mouse annulus fibrosus cells differentiated to three mesenchymal lineages. Furthermore, CD 146 positive annulus fibrosus cells became proliferative with hypoxia, TGF-beta 1 or R3-IGF1 stimuli suggesting its role as a useful differentiation marker for annulus fibrosus regeneration.
