骨髓间充质干细胞移植治疗肺气肿：静脉和气管途径谁更有优势？
Bone marrow mesenchymal stem cell transplantation for treatment of emphysema:intravenous versus intratracheal approach
摘要
Abstract
BACKGROUND:Bone marrow mesenchymal stem cel s transplantation can inhibit experimental emphysema inflammatory reaction and apoptosis, and has been experimental y confirmed to treat severe lung function impairment. OBJECTIVE:To explore the inhibitory effects of bone marrow mesenchymal stem cel s transplantation via different ways on inflammatory reaction and apoptosis due to experimental emphysema. METHODS:Female Wistar rats were randomly divided into control group, intravenous group and endotracheal group fol owing model establishment using fumigation plus intratracheal instil ation of porcine pancreatic elastase. In the latter two groups, bone marrow mesenchymal stem cel s from male rats were injected via the tail vein and the trachea, respectively. In the control group, rats were given PBS via he tail vein and trachea. At 14 days after transplantation, pathological changes of rat lung tissues were observed, cel apoptotic index in alveolar wal cel s and tumor necrosis factorαlevel in the bronchoalveolar lavage fluid were detected. RESULTS AND CONCLUSION:Compared with the control group, in the intravenous and endotracheal groups,the pathological changes of lung tissues were relieved, tumor necrosis factorαlevel and apoptosis index were reduced significantly (P<0.01);but there were no differences between the intravenous and endotracheal groups (P>0.05). These findings indicate that bone marrow mesenchymal stem cel s transplantation via the tail vein and trachea both can exert obvious therapeutic effects on emphysema. Moreover, cel transplantation via the tail vein is more convenient and easier than that via the trachea in the treatment of emphysema.关键词
