文题释义:
羟基磷灰石:
是一种生物活性材料,其结构与天然磷灰石矿物相近,具有与人体硬组织相似的结构和化学成分,是脊椎动物骨组织的主要无机成分,植入人体后,在体液作用下会被部分降解,释放出人体组织所必需的钙、磷元素并被人体组织吸收、利用,结合入新的组织,使羟基磷灰石植入物和人体骨组织获得良好的结合。
二氧化锆:是锆的主要氧化物,通常状况下为白色无臭无味晶体,难溶于水、盐酸和稀硫酸,一般常含有少量的二氧化铪,化学性质不活泼,且具有高熔点、高电阻率、高折射率和低热膨胀系数的性质,使它成为重要的耐高温材料、陶瓷绝缘材料和陶瓷遮光剂,亦是人工钻的主要原料。


背景:羟基磷灰石/二氧化锆组织工程骨可黏附成骨细胞、骨髓间充质干细胞及软骨细胞等多种细胞,诱导、促进骨折愈合或替代缺损骨质。
目的:综述羟基磷灰石/二氧化锆组织工程骨的发展历史及应用。
方法:应用计算机以“泡沫陶瓷、骨组织工程、骨形态发生蛋白、诱导性多能干细胞或porous bioceramic, bone tissue engineering, bone morphogenetic protein-2, induced pluripotent stem cells”为检索词,检索CNKI和PubMed数据库1971年1月至2014年12月发表的关于羟基磷灰石/二氧化锆组织工程骨应用的文章,最终选择54篇文章进行综述。
结果与结论:多孔羟基磷灰石/二氧化锆组织工程骨可引导新生骨组织长入三维孔隙内部,达到组织工程骨材料与自体骨组织的完美整合;用二氧化锆作为羟基磷灰石的增强体,通过调节材料的比例和孔隙率得到与人体骨弹性模量和断裂韧性均相似、结构相仿的高仿真人工骨材料;新型羟基磷灰石/二氧化锆泡沫陶瓷组织工程骨负载成骨诱导因子骨形态发生蛋白2壳聚糖凝胶缓释系统和iPSCs来源的骨髓间充质干细胞,可望明显提高其成骨性能和骨融合率。

Abstract:

BACKGROUND: Porous gradient hydroxyapatite/zirconia composite, which can adhere to a variety of cells, such as osteoblasts, bone marrow mesenchymal stem cells and chondrocytes, can induce and promote fracture healing or replace bone defects.
OBJECTIVE: To review the development and application of porous gradient hydroxyapatite/zirconia composite in bone tissue engineering.
METHODS: Articles related to porous gradient hydroxyapatite/zirconia composite in bone tissue engineering were retrieved in CNKI and PubMed databases (1971-01/2014-12). The key words were “porous bioceramic, bone tissue engineering, bone morphogenetic protein-2, induced pluripotent stem cells” in Chinese and English, respectively. A total of 54 articles based on inclusion criteria and exclusion criteria were obtained for the review.
RESULTS AND CONCLUSION: Porous gradient hydroxyapatite/zirconia composite can provide a scaffold to induce naturally forming bone growing to fill the three-dimensional pores, thus realizing the perfect integration of tissue-engineered bone material and host-bone tissue. As zirconia functions as an enhancer of hydroxyapatite, high-quality artificial bone materials, which have elastic modulus, fracture toughness and structure similar to human bone, can be prepared by adjusting the proportion and porosity of materials. Additionally, the new hydroxyapatite/zirconia foamed ceramics as tissue-engineered bone carrying bone morphogenetic protein-2/chitosan gel sustained release system and bone marrow mesenchymal stem cells derived from induced pluripotent stem cells will be expected to increase bone formation and bone fusion rates significantly in the future.

Key words: Tissue Engineering, Ceramics, Durapatite
