摘要
背景:石墨烯作为一种新兴的纳米材料被应用于各个领域,有许多研究发现基于石墨烯的纳米材料可以影响干细胞的生物学行为。目的:综述基于石墨烯的纳米材料在干细胞领域的应用及进展。方法:使用主题词及关键词检索PubMed、Web of Science及CNKI中国期刊全文数据库中收录的涉及基于石墨烯的纳米材料在干细胞领域应用的文献。英文检索词为"graphene,nanomaterials,stem cell",中文检索词为"石墨烯;纳米材料;干细胞",最终纳入57篇文献进行总结论述。结果与结论:基于石墨烯的纳米材料具有良好的稳定性和耐腐蚀性、较高的机械强度、良好的生物相容性,在生物医学中拥有广泛的应用前景。干细胞作为一种可以分化为人体内各种分化成熟细胞的未分化细胞,在组织工程、再生医学等领域具有广阔的应用前景。目前许多研究证明,基于石墨烯的纳米材料能影响干细胞的生物学行为,能促进各种干细胞的生长、增殖、黏附和分化,并且这些纳米材料可能通过调节相关基因表达、各种信号通路等方面影响干细胞的生物学行为。但基于石墨烯的纳米材料具有生物毒性,制约其在生物方面的应用,并且目前研究多在细胞层面,如何应用于生物体内仍需进一步研究。
BACKGROUND: As a kind of newly-developing nanomaterial, graphene has been used in many fields. Many recent studies have found that graphene-based nanomaterials can affect the biological behaviors of stem cells.OBJECTIVE: To review the application and progress of graphene-based nanomaterials in stem cells.METHODS: We searched the articles about the application of graphene-based nanomaterials in stem cells published in PubMed, Web of Science, and CNKI databases with the search terms "graphene, nanomaterials, stem cell" in English and Chinese. Finally, 57 articles met the criteria for review. RESULTS AND CONCLUSION: Graphene-based nanomaterials have good stability and corrosion resistance, high mechanical strength, good biocompatibility, which are accepted as one of the most promising nanomaterials in biomedicine. Stem cells are undifferentiated cells that can differentiate into various mature cells in human body, which have a broad application prospect in tissue engineering, regenerative medicine and other fields. Many recent studies have applied graphene-based nanomaterials to stem cell research and found that they can affect the growth, proliferation, adhesion and differentiation of stem cells, and these nanomaterials may affect the biological behavior of stem cells by regulating the expression of related genes and various signaling pathways. However, graphene-based nanomaterials have biological toxicity, which restrict their application in biological aspects. Moreover, most researches only involved cellular level, and it needs further animal studies and in vivo experimental researches.
