摘要
组织工程允许获取患者自己的细胞,并将其种植在生物可降解的支架上,从而获得一个特定的组织或器官,比如骨骼、软骨、肌腱甚至心脏,这些组织或器官可以用来修复由于疾病或创伤所致的组织或器官缺损。大量动物实验已证明骨髓间充质干细胞在治疗神经系统疾病、肝脏疾病、呼吸系统疾病和肾脏疾病等方面具有显著效果,治疗的主要途径是局部植入和全身移植,骨髓间充质干细胞比体细胞具有更高的增殖活性,因此将基因修饰的干细胞用于基因治疗前景广阔,可以很好的将基因和蛋白输送到那些需要的器官或组织中。
Tissue engineering may allow obtaining patient＇s own cells, seeding them on biodegradable scaffolds, thus achieving formation of a particular tissue or organs, such as bone, cartilage, muscle, or heart. These tissues or organs can be used to repair tissue or organs defects caused by disease or trauma. Many animal studies have demonstrated the efficacy of using bone marrow mesenchymal stem cells in treatment of diseases such as nervous system diseases, liver disease, respiratory diseases and kidney disease. The main ways of the stem cells therapy are local implantation and systemic transplantation of bone marrow mesenchymal stem cells, and the effect of such treatments is notable. The use of gene-modified stem cells in gene therapy is an fantastic option due to theoretical advantage of stem cells compared to somatic cells with respect to higher proliferative capacity. Bone marrow mesenchymal stem cells can deliver genes and proteins into organs or tissues with specific need for gene therapy.
