文题释义:
骨髓间充质干细胞:
是存在于骨髓中具有高度自我更新能力和多向分化潜能的非造血干细胞且可在特定的环境中定向分化为成骨细胞、血管内皮细胞、成软骨细胞、脂肪细胞、肌腱细胞等,是目前组织工程中最常用的种子细胞之一。
Bio-oss人工骨:是一种从牛骨中提取,经过特殊加工处理,除去蛋白和其他有机成分,高纯度并且保持多孔天然骨无机结构,同人体骨的结构几乎相同的生物移植材料。实验及临床研究证实,Bio-oss具有非常好的生物相容性,能满足骨引导材料的标准。Bio-oss植入体内可以降解吸收并逐渐被新生骨取代。

 

摘要
背景:
目前有一些关于骨髓间充质干细胞复合异体骨、人工合成骨替代材料促进骨缺损修复的研究,但尚未见骨髓间充质干细胞复合Bio-oss用于兔颅骨缺损修复的报道。
目的:观察骨髓间充质干细胞复合Bio-oss修复兔颅骨缺损的效果。
方法:分离培养雄性兔骨髓间充质干细胞,将其作为种子细胞,在雌兔颅骨采用外直径6 mm的环形骨钻制造全层骨缺损3个。将96只雌性兔随机等分为4组,复合物组植入Bio-oss复合骨髓间充质干细胞,Bio-oss组单纯植入Bio-oss,骨髓间充质干细胞组单纯植入骨髓间充质干细胞,空白组不进行植入修复。每个组表面均覆盖引导组织再生膜。
结果与结论:复合物组成骨效果比其他3组更佳,Bio-oss组成骨效果比骨髓间充质干细胞组和空白组更好,骨髓间充质干细胞组与空白组成骨效果接近。说明以骨髓间充质干细胞作为种子细胞,Bio-oss作为支架材料复合植入兔颅骨缺损区有明显的促进成骨作用,为临床治疗骨缺损提供新思路。

Abstract:

BACKGROUND: Some studies have focused on bone marrow mesenchymal stem cells (BMSCs) combined with allograft bone or artificial bone substitute materials for bone defect repair. But there is no report on BMSCs combined with Bio-oss for repair of rabbit skull defects as yet.
OBJECTIVE: To observe the effect of BMSCs combined with Bio-oss in repairing skull defects in rabbits.
METHODS: BMSCs from male rabbits were isolated, cultured, and used as seed cells. In the skull of the female rabbits, three full-thickness bone defects with the same external diameter of 6 mm were made by a ring bone drill. Ninety-six female rabbits were randomly divided into four groups, and given Bio-oss/BMSCs in combination group, Bio-oss alone in Bio-oss group, BMSCs implantation in BMSCs group, and no intervention in blank group. All the implant surfaces were covered with guided tissue regeneration membrane.
RESULTS AND CONCLUSION: The osteogenic effect in the combination group was better than that in the other three groups, and the Bio-oss group showed better osteogenesis in comparison with BMSCs and blank groups. But there was no significant difference between the BMSCs and blank groups. These findings indicate that the combined use of BMSCs as seed cells and Bio-oss as a scaffold material exerts overt osteogenic effects in rabbit skull defect area, which provides a new idea for the clinical treatment of bone defects.
