摘要:


文题释义:

缺血性脑卒中:多发于中老年人,具有发病率、致残率及致死率高的特点,是由于血管阻塞造成血流量供应减少和组织缺氧,最终导致神经功能障碍。
骨髓间充质干细胞:是一种多能干细胞,具有自我更新、分化、分泌及归巢的特点,可分化为神经元、星形胶质细胞、少突胶质细胞等,具有低免疫原性、易扩增等特点。


背景:骨髓间充质干细胞(bone marrow mesenchymal stem cells,BMSCs)已被广泛用于治疗神经系统疾病,但由于血脑屏障的限制以及干细胞在受损部位存活率、分化率低,导致治疗效果有限。

目的:探讨麝香黄芪复方滴丸含药血清对BMSCs增殖、迁移和向星形胶质细胞分化的影响。
方法:SD雄性大鼠连续灌胃麝香黄芪复方滴丸5 d后进行腹主动脉取血,分离血清备用。采用CCK-8法检测体积分数5%,10%,20%含药血清对BMSCs增殖的影响;划痕实验观察体积分数10%含药血清对BMSCs横向迁移的影响;Transwell小室培养BMSCs,用结晶紫染色和DAPI核染色观察体积分数10%含药血清对BMSCs纵向迁移的影响;用含体积分数10%含药血清的诱导液或与星形胶质细胞共培养观察BMSCs向星形胶质细胞分化情况。

结果与结论:①体积分数10%和20%含药血清在第2,3天促进细胞增殖更明显,且两种体积分数无统计学差异;②在划痕30,48 h时,10%含药血清组BMSCs迁移量显著高于对照组;③10%含药血清组BMSCs穿过Transwell小室滤过膜的数量高于对照组;④体积分数10%含药血清可能促进BMSCs向星形胶质细胞方向分化,但分化作用较弱,星形胶质细胞能进一步促进含药血清诱导BMSCs向星形胶质细胞方向分化;⑤结果表明,体积分数10%含药血清能促进BMSCs体外增殖、迁移;与星形胶质细胞共培养可能促进BMSCs向星形胶质细胞方向分化。

Abstract: BACKGROUND: Bone marrow mesenchymal stem cells have been widely used to treat neurological diseases. However, due to limitations of the blood-brain barrier, low survival rate and differentiation rate of stem cells at damaged sites, the therapeutic effect is limited.
OBJECTIVE: To investigate the effects of Shexiang Huangqi compound dripping pills on proliferation, migration and astrocyte differentiation of bone marrow mesenchymal stem cells.
METHODS: Male SD rats were treated with Shexiang Huangqi compound dripping pills for 5 days after continuous gavage. Blood was collected from the abdominal aorta and serum was separated for later use. The effect of 5%, 10% and 20% drug-containing serum on the proliferation of bone marrow mesenchymal stem cells was detected by CCK-8 assay. The effect of 10% drug-containing serum on lateral migration of bone marrow mesenchymal stem cells was observed by scratch test. Bone marrow mesenchymal stem cells were cultured in Transwell cells. The effects of 10% drug-containing serum on longitudinal migration of bone marrow mesenchymal stem cells were observed by crystal violet staining and DAPI nuclear staining. Differentiation of bone marrow mesenchymal stem cells into astrocytes was observed by inducing solution with 10% drug-containing serum or co-culture with astrocytes. 
RESULTS AND CONCLUSION: (1) 10% and 20% drug-containing serum promoted cell proliferation more significantly on days 2 and 3, and there was no statistical difference between the two concentrations. (2) At 30 and 48 hours, bone marrow mesenchymal stem cell migration in 10% drug-containing serum group was significantly higher than that in the control group. (3) The number of bone marrow mesenchymal stem cells filtered through Transwell cells in 10% drug-containing serum group was higher than that in the control group. (4) 10% drug-containing serum might promote the differentiation of bone marrow mesenchymal stem cells to astrocytes, but the differentiation effect was weak, and astrocytes might further promote the differentiation of bone marrow mesenchymal stem cells into astrocytes induced by drug-containing serum. (5) The results exhibited that the 10% drug-containing serum could promote the proliferation and migration of bone marrow mesenchymal stem cells in vitro. Co-culture with astrocytes may promote the differentiation of bone marrow mesenchymal stem cells towards astrocytes.
