文题释义:
血管组织工程:利用血管壁的正常细胞和生物可降解材料来制备、重建和再生血管的科学。
骨髓间充质干细胞:是最早发现的间充质干细胞,来源于发育早期的中胚层和外胚层,具有多向分化潜能、造血支持和促进干细胞植入、免疫调控和自我复制等特点。

目的:观察4种静电纺丝膜材料对骨髓间充质干细胞增殖、黏附及分化为血管平滑肌细胞的影响。
方法:分离提取SD大鼠骨髓间充质干细胞。将骨髓间充质干细胞分别接种于聚己内酯(PCL)、聚己内酯-透明质酸(PCL-HA)、聚己内酯-丝素蛋白(PCL-SF)、聚己内酯-明胶(PCL-GEL)静电纺丝膜材料上,培养1,3,7 d后,扫描电镜下观察材料上的细胞排布,鬼笔环肽染色观察材料上的细胞增殖与黏附,qRT-PCR检测材料上细胞分泌的CD90、Meflin、转化生长因子β mRNA表达;向血管平滑肌细胞诱导分化7 d后,qRT-PCR检测材料上细胞ɑ-平滑肌肌动蛋白mRNA表达。
结果与结论:①扫描电镜下可见骨髓间充质干细胞在4种静电纺丝膜上均沿着静电纺丝膜的纤维走向排列;②鬼笔环肽染色显示,骨髓间充质干细胞在4种静电纺丝膜上分布规律,均沿着纤维走向呈现平行分布,并且PCL-HA、PCL-SF、PCL-GEL静电纺丝膜较PCL静电纺丝膜更有利于骨髓间充质干细胞的增殖、黏附,PCL-SF静电纺丝膜相较于PCL-HA、PCL-GEL静电纺丝膜更有利于骨髓间充质干细胞的增殖、黏附;③qRT-PCR检测显示,4种静电纺丝膜材料均可维持骨髓间充质干细胞CD90和Meflin的mRNA表达,组间比较差异无显著性意义(P > 0.05);PCL-HA、PCL-SF、PCL-GEL组培养1,7 d的转化生长因子β mRNA表达高于PCL组(P < 0.05),PCL-SF组培养3,7 d的转化生长因子β mRNA表达高于其他3组(P < 0.05),PCL-HA组培养7 d的转化生长因子β mRNA表达高于PCL-GEL组(P < 0.05);④qRT-PCR检测显示,PCL-SF组ɑ-平滑肌肌动蛋白mRNA表达高于其他3组(P < 0.05),PCL-HA组ɑ-平滑肌肌动蛋白mRNA表达高于PCL组(P < 0.05);⑤结果表明:相较于PCL、PCL-HA、PCL-GEL静电纺丝膜,PCL-SF静电纺丝膜与骨髓间充质干细胞结合更适合制备小口径组织工程血管。

Abstract: BACKGROUND: Small diameter artificial vessels are urgently needed to treat coronary artery and peripheral artery diseases in clinical practice. At present, vascular tissue engineering has become the main method for preparing small diameter artificial vessels. Selecting suitable biomaterials and cell sources is the key factor for successful construction of small diameter tissue engineered vessels. 
OBJECTIVE: To observe the effect of four kinds of electrospinning membrane materials on proliferation, adhesion and differentiation of bone marrow mesenchymal stem cells into vascular smooth muscle cells. 
METHODS: Bone marrow mesenchymal stem cells were isolated and extracted from SD rats. The bone marrow mesenchymal stem cells were inoculated separately on polycaprolactone (PCL), polycaprolactone-hyaluronic acid (PCL-HA), polycaprolactone-silk-filament proteins (PCL-SF), and polycaprolactone-gelatin (PCL-GEL) electrospinning membrane materials. After 1, 3, and 7 days of culture, the cell arrangement on the material was observed under scanning electron microscope. The proliferation and adhesion of the material were observed by phalloidin staining. The mRNA expressions of CD90, Meflin, and transforming growth factor β were detected by qRT-PCR. After 7 days of induced differentiation into vascular smooth muscle cells, the mRNA expression of ɑ-smooth muscle actin on the material was detected by qRT-PCR.
RESULTS AND CONCLUSION: (1) Bone marrow mesenchymal stem cells were arranged along the fibers of the four kinds of electrospinning membranes under scanning electron microscopy. (2) Phalloidin staining showed the regular distribution of bone marrow mesenchymal stem cells on the four kinds of electrospinning membranes and parallel distribution along the fiber direction. Moreover, PCL-HA, PCL-SF, and PCL-GEL electrospinning membranes were more conducive to the proliferation and adhesion of bone marrow mesenchymal stem cells than PCL electrospinning membranes. Compared with PCL-HA and PCL-GEL electrospinning membranes, PCL-SF electrospinning membranes were more conducive to the proliferation and adhesion of bone marrow mesenchymal stem cells. (3) qRT-PCR showed that the four kinds of electrospun membrane materials could maintain the mRNA expression of CD90 and Meflin in bone marrow mesenchymal stem cells, but there was no significant difference between groups (P > 0.05). The mRNA expression of transforming growth factor β in PCL-HA, PCL-SF, and PCL-GEL groups was higher than that in PCL group on days 1 and 7 (P < 0.05), and the mRNA expression of transforming growth factor β in PCL-SF group was higher than that in the other three groups on days 3 and 7 (P < 0.05). The mRNA expression of transforming growth factor β in PCL-HA group was higher than that in PCL-GEL group on day 7 (P < 0.05). (4) qRT-PCR showed that the mRNA expression of ɑ-smooth muscle actin in PCL-SF group was higher than that in the other three groups (P < 0.05), and that in PCL-HA group was higher than that in PCL group (P < 0.05). (5) The results indicate that compared with PCL, PCL-HA and PCL-GEL electrospinning membranes, PCL-SF electrospinning membranes combined with bone marrow mesenchymal stem cells are more suitable for the preparation of small diameter tissue engineered vessels.
