摘要
[目的]探讨骨髓间充质干细胞(BMSCs)静脉移植对大鼠脊髓损伤后神经功能恢复的影响。[方法]利用多中心急性脊髓损伤打击器(MASCIS Impactor)建立大鼠T11脊髓损伤模型,建模成功后随机分为两组:对照组(A组)、BMSCs移植组(B组)。SCI后1周,A组自大鼠尾静脉注射无血清的DMEM/F12培养液0.1 ml,B组自大鼠尾静脉注射移植BMSCs悬液0.1 ml。两组大鼠于SCI后1、2、4、8周行BBB后肢运动功能评分,SCI后2、4、8周行SEP检测及脊髓组织病理学检查(HE染色与NF200免疫组化染色)。[结果]SCI后2、4、8周,与A组比较,B组BBB评分升高,SEP N1潜伏期缩短、P1-N1波幅增高,差异均有统计学意义(P<0.01);SCI后8周大鼠脊髓组织HE染色显示,两组大鼠脊髓组织损伤区均可见瘢痕组织及空洞形成,但B组脊髓空洞比A组小;SCI后2、4、8周,NF200免疫组化染色显示,两组大鼠脊髓组织均有NF200阳性表达,与A组比较,B组各时间点NF200阳性表达均增强,差异有统计学意义(P<0.01)。[结论]BMSCs静脉移植对大鼠SCI后神经功能的恢复有明显的促进作用。
