The subject invention concerns a method of introducing at least one DNA sequence expressing a protein or protein fragment which substantially alleviates articular cartilage defects. This method involves in vitro culture of chondrocytes, transfection of the chondrocytes with a recombinant vector housing the DNA sequence to be expressed, and delivery of the transfected chondrocytes to the damaged cartilage region. This method can also be used in tandem with synovial cell delivery techniques of the present invention. This method is also useful as a model in animal studies regarding joint pathologies.
本发明涉及一种引入至少一种表达蛋白质或蛋白质片段的 DNA 序列的方法,这种蛋白质或蛋白质片段可大大缓解关节软骨缺损。该方法包括体外培养软骨细胞,用含有待表达 DNA 序列的
重组载体转染软骨细胞,以及将转染的软骨细胞输送到受损的软骨区域。这种方法也可与本发明的滑膜细胞递送技术结合使用。这种方法还可用作关节病理学动物研究的模型。
