由于肌膜修复缺陷,Dysferlin 缺乏会导致一种特殊形式的肌营养不良症,目前缺乏治疗方法。我们开发了一种使用野生型成年小鼠中成血管细胞的细胞治疗方案。这些细胞在体外高效分化为骨骼肌,但与卫星细胞不同,因为它们不表达 Pax7。对 SCID/BlAJ 小鼠(一种新的 Dysferlin 病模型)进行肌内或动脉内给药后,野生型中成血管细胞有效地在营养不良的肌肉中定殖,并部分恢复 Dysferlin 的表达。然而,对移植肌肉中分离出的单纤维进行的功能测定显示,激光诱导损伤后膜具有正常的修复能力;这一结果反映了酶促基因纠正而不是结构缺陷,表明这种肌病可能比其他形式的肌营养不良症更容易用细胞或基因疗法治疗。
Dysferlin deficiency leads to a peculiar form of muscular dystrophy due to a defect in sarcolemma repair and currently lacks a therapy. We developed a cell therapy protocol with wild-type adult murine mesoangioblasts. These cells differentiate with high efficiency into skeletal muscle in vitro but differ from satellite cells because they do not express Pax7. After intramuscular or intra-arterial administration to SCID/BlAJ mice, a novel model of dysferlinopathy, wild-type mesoangioblasts efficiently colonized dystrophic muscles and partially restored dysferlin expression. Nevertheless, functional assays performed on isolated single fibers from transplanted muscles showed a normal repairing ability of the membrane after laser-induced lesions; this result, which reflects gene correction of an enzymatic rather than a structural deficit, suggests that this myopathy may be easier to treat with cell or gene therapy than other forms of muscular dystrophies.
