    • The subject invention is related to a cell-mediated gene therapy treatment for orthopedic disease using a member belonging to the transforming growth factor- beta (TGF- beta ) superfamily. TGF- beta gene therapy as a new treatment method for degenerative arthritis is demonstrated. After transfection of TGF- beta cDNA expression vectors into fibroblasts (NIH 3T3-TGF- beta 1), the cells were injected into rabbit achilles tendon and knee joints with artificaslly-made cartilage defects. Intratendinous injections were performed to determine the optimal concentration of in vivo expression. Partially defected cartilage model was made to stimulate degenerative arthritis of the knee joint. The partial cartilage defect treated with the cell-mediated gene therapy procedure was covered by newly formed hyaline cartilage which indicates the cells survived and stimulated matrix formation in this area. Completely denuded cartilage areas were covered by fibrous collagen.
    • 本发明涉及使用属于转化生长因子-β(TGF-β)超家族的成员的骨科疾病的细胞介导的基因治疗治疗。 证实了TGF-β基因治疗作为退行性关节炎的新治疗方法。 将TGF-βcDNA表达载体转染到成纤维细胞(NIH 3T3-TGF-β1)后,将细胞注射到兔子跟腱和膝关节与人造软骨缺损。 进行Intratendinous注射以确定体内表达的最佳浓度。 部分缺损的软骨模型被用来刺激膝关节退行性关节炎。 用细胞介导的基因治疗方法处理的部分软骨缺损被新形成的透明软骨覆盖,表明细胞存活并刺激该区域的基质形成。 完全剥落的软骨区域被纤维胶原覆盖。
