文题释义:
石墨烯:由碳原子以sp2杂化轨道而形成的单层二维平面晶体,是目前世界上发现的最薄的新型纳米材料,具有较好的稳定性、导电性、导热性、机械强度,已在生物医学、组织工程学广泛应用。
石墨烯对间充质干细胞的影响:一方面,由于石墨烯对间充质干细胞或成骨细胞的毒性较小,甚至没有毒性,因此可提高这些细胞在石墨烯材料上的吸附和增殖;另一方面,石墨烯具有较强的非共价结合能力,使之作为成骨诱导剂的富集平台,进而能够诱导骨髓间充质干细胞的成骨分化。
 
 
背景:石墨烯具有良好的生物相容性和高机械强度,已在组织工程学中广泛应用。
目的:综述石墨烯的一般性质、降解性能、生物相容性及在骨组织工程中的应用。
方法:应用计算机检索CNKI数据库、PubMed数据库及Elsevier数据库的2000年1月至2018年4月发表的相关文献,检索词为“石墨烯,石墨烯衍生物,组织工程,骨组织工程;graphene,graphene derivatives,tissue engineering,bone tissue engineering”。通过阅读文题和摘要进行初步筛选,排除与文章主题不相关的文献,根据纳入标准和排除标准,最终纳入65篇文献进行结果分析。

结果与结论:①石墨烯具有良好的生物相容性、可降解性,细胞毒性较弱,对细胞增殖无明显影响,可作为组织工程支架搭载细胞,使其在上面生长;②石墨烯及其衍生物能够促进间充质干细胞的生长和成骨分化,对于修复骨缺损和骨再生有明显的促进作用,能够应用于骨组织工程的研究;③石墨烯和其他聚合物、矿物质或金属结合后能够改善其性能,可进一步促进其成骨分化的能力。

Abstract:

BACKGROUND: Graphene has good biocompatibility and high mechanical strength, which has been widely used in tissue engineering.

OBJECTIVE: To review the general properties, degraded properties, biocompatibility, and application of graphene in bone tissue engineering
METHODS: A computer-based search of CNKI, PubMed, and Elsevier was performed for retrieving articles concerning the application of graphene in bone tissue engineering published from January 2000 to April 2018. The keywords were “grapheme, graphene derivatives, tissue engineering, bone tissue engineering” in Chinese and English, respectively. The preliminary screening was carried out by reading titles and abstracts, and according to inclusion and exclusion criteria, 65 articles were finally included for result analysis after removal of unrelated articles.

RESULTS AND CONCLUSION: (1) Graphene has good biocompatibility, degradability, weak cytotoxicity, and has no obvious effect on cell proliferation. Therefore, graphene can be used as a tissue engineering scaffold to carry cells that can grow on the scaffold surface. (2) Graphene and its derivatives can promote the growth and osteogenic differentiation of mesenchymal stem cells, and have a significant role in the repair of bone defects and bone regeneration. Therefore, they can be applied in bone tissue engineering. (3) Graphene combined with other polymers, minerals or metals can improve their performance, and can further promote the osteogenic differentiation.

Key words: Bone Regeneration, Stem Cells, Tissue Engineering
