Research Abstract

全長10型コラーゲン遺伝子を含むbacterial artificial chromosome(BAC)DNAの10型コラーゲンプロモーター領域下流にSox9 cDNAを挿入し、Sox9を肥大化軟骨層に異所性に過剰発現するBACトランスジェニックマウスを作製し,(1) 骨髄の消失、肥大化軟骨層への血管侵入の遅延、肥大化軟骨細胞層の延長に起因する骨の短縮、(2) 延長した肥大化軟骨細胞層でのSox9の強い発現に加え、肥大化軟骨マーカー遺伝子の発現の低下、(3) Sox9は直接的にyθgfプロモーター活性を低下させる事、を明らかにし、これらの事からSox9の肥大軟骨細胞層における消失は、血管の侵入、骨髄の形成を可能にし,正常な内軟骨性骨形成に必須である事をin vivoおよびin vivoで明らかにした。
