摘    要:目的:观察移植骨髓间充质干细胞(BMSCs)对溃疡性结肠炎(UC)大鼠结肠病变的修复.方法:分离培养、荧光标记SD大鼠BMSCs.A,B,C组大鼠制作UC模型,D组为非模型组.4组大鼠均经尾静脉注射1 mL液体:A组为生理盐水;B,D组为BMSCs;C组为加表皮生长因子(EGF)的BMSCs.移植后3,7,14 d各处死5只大鼠,荧光显微镜下观察荧光标记BMSCs在结肠的分布,光镜观察结肠病变以及TNF-α和IL-10的表达.结果:移植第3日各组均可见BMSCs分布于结肠黏膜,病灶处多于正常结肠黏膜.移植第14日,B,C组结肠BMSCs高于D组(P〈0.05);与A组比较,B,C组结肠黏膜高表达IL-10,低表达TNF-α,其黏膜损伤修复程度也明显优于A组.B,C组间差异不明显(P〉0.05).结论:移植BMSCs可促进UC大鼠结肠损伤的修复.单次给予EGF不能促进BMSCs向病灶的迁移和损伤的修复.

关 键 词:骨髓间充质干细胞  移植  溃疡性结肠炎

Abstract:AIM:To investigate the reparation of bone marrow mesenchymal stem cell-transplantation for the ulcerative colitis rat.METHODS:The BMSC of SD rat were isolated,cultured and labelled with fluor.SD rats were randomly distributed into 4 groups,Colitis was induced with immune-combined TNBS/ethanol in group A,B and C,but was not induced in group D.Following the induction of colitis,each rat in 4 groups received caudal vein injection of 1 mL fluids,which were:normal sodium for group A,BMSCs for group B and D,BMSCs...
Keywords:bone marrow mesenchymal stem cells  transplantation  ulcerative colitis
