摘要 目的:探讨移植人脐带间充质干细胞修复大鼠脊髓损伤的疗效。方法:选择健康成年雄性大鼠80只,体重200~250g。随机分为2组:研究组和对照组,研究组和对照组均行脊髓左侧半切。研究组在损伤后72小时移植人脐带间充质干细胞。对比(1)研究组和对照组术后2周、4周改良Tarlov评分。(2)研究组和对照组组织学变化。结果:(1)研究组和对照组术后2周、4周改良Tarlov评分结果比较有差异(P〈0.05)。(2)对照组在手术后8周提示脊髓空洞面积大、神经纤维稀疏,炎性细胞和星型胶质细胞聚集,见图1。研究组在手术后8周提示脊髓周围炎症细胞和胶质细胞明显减少,有神经纤维通过损伤区。结论:本次研究认为移植人脐带间充质干细胞能抑制胶质瘢痕形成,
