目的：探讨骨髓间充质干细胞移植对脑出血大鼠的行为和血肿周围神经细胞凋亡的影响。方法全骨髓贴壁法分离培养大鼠骨髓间充质干细胞，使用立体定向纹状体注入胶原酶法制作大鼠脑出血模型。 SD大鼠30只，随机分为对照组和移植组（各15只），对照组制作脑出血模型，不移植；移植组制作脑出血模型并于造模后48h经立体定向脑内注射1×105个干细胞，并于移植后1d、3d、5d、7d、14d进行神经功能缺损评分，对照组在相应时间点同样评分，各组再根据时间的不同随机分成五个亚组（每组3只），在相应时间点处死大鼠行免疫组织化学法检测细胞凋亡。结果在移植后1 d、3 d，两组大鼠评分及血肿周围脑组织内凋亡细胞的数量均较高，两组之间无显著性差异。在移植后第5 d、7 d，两组大鼠评分及血肿周围脑组织内凋亡细胞的数量开始下降，移植组下降幅度大于对照组，两组之间差异显著。移植后14 d，两组之间无显著性差异。结论骨髓间充质干细胞移植可明显促进大鼠脑出血后神经功能的恢复，其机制可能与下调血肿周围神经细胞凋亡有关。

Objective To explore the effect of the behavioral test and neurological cell apoptosis on transplantation of bone mesenchymal stem cells (BMSCs) for experimental intracerebral hemorrhage (ICH) in rats.Methods BMSCs were isolated and cultured using the whole bone marrow adherent method.A rat model of ICH was established by stereotaxical injection of collagenase Ⅰinto the right caudate nucleus .30 Sprague-Dawley ( SD ) rats were randomly divided into control group ( 15 ) and transplantation group (15).The control group were injected with collagenaseⅠonly,the transplant-ation group were transfused with BMSCs (1 ×105/rat) at 48 hours after surgery .On 1,3,5,7,14 days afer transplantation neurological function tests were performed among all groups and animals were sacrificed at the corresponding time points for detecting the neurological cell apoptosis .Results On 1,3 days after transplantation ,neurological function tests score and neurological cell apoptosis of two groups are not different .On 5,7 days after transplantation ,neurological function tests score and neurological cell apoptosis of two groups are significantly different .On 14 days after transplantation , neurological function tests score and neurological cell apoptosis of two groups have no difference .Conclusion Transplantation of BMSCs could significantly promote the neurological function recovery of ICH rats , which might be associated with its downregulation of neurological cell apoptosis .
