治疗基因局部转染修复关节软骨损伤的研究进展

关节软骨损伤、退变或其他病变时均可导致软骨面的缺损，缺损后依靠自身修复的能力很低。作者对利用治疗基因修饰的种子细胞构建组织工程化软骨，或局部转移目的基凶至靶细胞，选择合适的治疗基因、靶细胞及基因导入系统，在缺损区表达治疗剂量的活性基因产物进行了综述，为关节软骨缺损的生物学修复提供新的治疗手段。

Gene therapy in reparation of cartilage lesions

Damaged articular cartilage has a limited intrinsic capacity to heal itself,especially in adults,It represents a clinical challenge.Novel gene therapy can introduce particular beneficial gene into the seeded sells and express growth factors or other therapy proteins at the repair site.Gene therapy focuses on selecting proper gene,target cells and the transferring systems. The tissue engineering cartilage with gene-modified seeding cells and transferring objective gene to target sells locally present new therapeutic regimens for repairing defects in articular cartilage.
