背景:为解决骨髓间充质干细胞体内分化效率低的问题,拟联合Shootin1基因修饰,希望能有效提高脊髓损伤区内骨髓间充质干细胞神经分化的能力,增加细胞移植治疗脊髓损伤的效果。目的:探讨过表达Shootin1的骨髓间充质干细胞移植修复脊髓损伤模型大鼠的神经再生能力。方法:(1)通过腺病毒转染48 h,使骨髓间充质干细胞过表达Shootin1;(2)在体外进行神经诱导分化,免疫荧光检测神经巢蛋白(Nestin)与神经元特异性核蛋白(NeuN)的表达;(3)运用改良Allen撞击装置制备脊髓撞击损伤模型,造模后半小时在蛛网膜下腔注射Shootin1转染的骨髓间充质干细胞和未转染骨髓间充质干细胞,脊髓损伤对照组仅进行脊髓损伤手术。脊髓损伤5周后取脊髓样本进行冰冻切片检测神经相关标记。结果与结论:(1)腺病毒转染48 h,免疫荧光与Western Blot检测骨髓间充质干细胞内已成功表达Shootin1蛋白;(2)体外神经诱导分化7 d,3组细胞形态上均发生了变化,Shootin1转染的骨髓间充质干细胞组和未转染骨髓间充质干细胞组Nestin与NeuN的表达差异不明显;(3)脊髓撞击损伤大鼠体内实验发现,与对照组相比,细胞移植组BBB评分增高。移植Shootin1转染的骨髓间充质干细胞组和未转染骨髓间充质干细胞组均有Nestin,NeuN,GFAP,MAP-2,ChAT,SYN表达的升高,神经再生能力增强。(4)实验再次认证了骨髓间充质干细胞移植治疗脊髓损伤的显著性效果,Shootin1蛋白对脊髓损伤后的神经再生及神经功能性恢复起到一定作用,但其对于骨髓间充质干细胞直接移植来说修复差异仍不太明显,优化骨髓间充质干细胞对脊髓损伤的治疗仍需进一步研究。
