摘　　要：目的获得血管组织工程的实验依据。方法获取大鼠血管内皮(VEC)和平滑肌细胞(VSMCs),进行培养扩增,然后接种到血管组织工程支架上;将VSMCs-血管支架移植到大鼠体内,观察移植后大鼠活体和组织病理反应。结果培养的细胞符合血管种子细胞的形态特征;VSMCs接种到血管组织工程支架上获得成功;VSMCs-血管支架移植到大鼠体内10d后,支架被纤维组织包裹,支架内见VSMCs生长,支架中央管腔存在,但与正常血管结构有很大差别,而且不具备血管功能。结论利用血管组织工程支架构建的大鼠VSMCs-血管支架移植到大鼠皮下是可行的;人工构建血管具有类似血管雏形,但尚不具备血管的正常结构。Objective To obtain the experimental data of vascular tissue engineering. Methods The vascular endothelial cells （VEC） and vascular smooth muscle cells （VSMCs） were acquired and cultured, and then seeded on vascular tissue engineering materials. The porous gelatin-chitosan scaffold with VSMCs was subcutaneously implanted, followed by the observation of the cell growth ten days later. Results The two kinds of cells were successfully cultured and their morpholoical and immunohistochemical characteristics were consistent with vascular endothelial and VSMCs respectively. The VSMCs could grow extensively on the scaffold after the in vivo implantation. The scaffold were wrapped by the fibrous tissue ten days later after the in vitro implantation of VSMCs. The seed cells grew in the scaffold, and the vessel cavity seen in the center of the scaffold, was quite different from the normal vessel structure. Conclusion It is feasible to implant the VSMCs with fibrin gels into the living body. The vessels reconstructed, though different from the normal structure, is similar to the embryo of the vessels.
