摘要:

背景:Duchenne型肌营养不良症是一种累及肌肉系统的致死性遗传疾病,迄今尚无有效治疗方法。近年来学者们针对干细胞治疗Duchenne型肌营养不良症进行了基础研究和动物实验,在此基础上又进行了有意义的临床试验。
目的:观察Duchenne型肌营养不良症患儿接受序贯式干细胞移植治疗前后,其运动功能、肌细胞修复与再生、抗肌萎缩蛋白表达和缺失基因替代的变化,评价治疗的可行性和安全性。
方法:于2009-05应用序贯式干细胞移植治疗1例8岁男性Duchenne型肌营养不良症患儿,多重连接探针扩增方法基因分析13外显子缺失。序贯式干细胞移植,即依次行脐带间充质干细胞经静脉内移植-肌肉内移植-单倍体异基因造血干细胞移植。定期检测血清酶学变化、供者HLA植入证据、缺陷基因表达、肌细胞膜抗肌萎缩蛋白表达、运动功能改善情况。
结果与结论:序贯式干细胞移植治疗Duchenne型肌营养不良症,可使缺失基因替代,肌细胞膜dystrophin阳性表达,血清酶学显著降低,进一步提高运动功能。可阻止Duchenne型肌营养不良症患儿疾病进展,有望获得持续性改善。

Abstract:

BACKGROUND: Duchenne muscular dystrophy (DMD), a well-known genetic lethal in humans, cannot be effectively cured at present. Recently, scholars have performed basic research and animal trials using stem cells for treatment of DMD, and also conduct significant clinical studies.
OBJECTIVE: To investigate the feasibility and safety of therapy in patients with DMD who received stem cell transplantation in sequence by observing the change of their motor function, muscle cytothesis and regeneration, expression of dystrophin and altering of depletion gene.
METHODS: An 8-years old boy with DMD was treated by stem cell transplantation in sequence in May 2009. Exon 13 was depleted by multiplex ligation-dependent probe amplification. Stem cell transplantation in sequence was as follows: First, intravenous umbilical cord mesenchymal stem cell (UC-MSC) transplantation; Second, intramuscular UC-MSC transplantation; finally, monoploid allogene hemopoietic stem cell transplantation. Sero-enzyme, implantation proof of donor HLA antigen, expression of depletion gene and dystrophin of myocyte membrane, motor function were detected after transplantation.
RESULTS AND CONCLUSION: By stem cell transplantation in sequence for DMD, depletion gene could be substituted. Dystrophin of myocyte membrane expresses; sero-enzyme steps down significantly; motor function is improved. It could prevent the progression of disease and patient’s condition is to be ameliorated continuously.
