- Abstract: BACKGROUND:Graphene is the thinnest,strongest,and toughest type of two-dimensional new crystal material,demonstrating significant advantages in biomedical applications.Angiogenesis and vascularization of bone are key factors in tissue repair and regeneration,and are effective ways to address vascular and osteogenic issues. OBJECTIVE:To review the characteristics and mechanisms of graphene and its derivatives in promoting angiogenesis activity and vascularizing bone,in order to provide a reference for their clinical application in vascular tissue repair and regeneration. METHODS:Using a computer to search for relevant literature included in PubMed,ScienceDirect,CNKI,and Wanfang databases,the Chinese search terms were"grapheme","angiogenesis,vascularization","vascularized bone",and"endothelial cells",while the English search terms were"graphene""angiogenesis OR vascularization""vascularized bone""endothelial cells".After excluding literature unrelated to the topic of the article,according to the inclusion and exclusion criteria,62 articles were ultimately included for result analysis. RESULTS AND CONCLUSION:(1)At present,graphene oxide has been studied more and is the most widely used in graphene and its derivatives.(2)Graphene and its derivatives are suitable for heart,bone,nerve,and wound healing related diseases.(3)Graphene and its derivatives have excellent physical and chemical properties and biological properties,but they have potential cytotoxicity.We should pay attention to its biological safety in application.(4)The application of graphene and its derivatives requires further research to demonstrate the optimal size and concentration and measures to reduce toxicity.(5)On the cellular level,graphene and its derivatives can promote angiogenic activity by tip endothelial cell phenotype,mesenchymal stem cell adhesion and proliferation, and vascular smooth muscle cell growth.(6)On the molecular level,graphene and its derivatives can increase the expression of vascular endothelial growth factor,basic fibroblast growth factor,hepatocyte growth factor and activate reactive oxygen species/nitric oxide synthase/nitric oxide signaling pathway,lysophosphatilate R6/Hippo-YAP pathway,stromal cell-derived factor-1/vascular endothelial growth factor and ZEB 1/Notch1 pathway.(7)Grapheme oxide and graphene oxide-copper phosphorylated extracellular regulatory protein kinase and activated hypoxia-inducible factor-1,thereby promoting the up-regulation of vascular endothelial growth factor and bone morphogenetic protein-2 expression,and promoting angiogenesis and vascularized bone.(8)In summary,graphene and its derivatives,especially graphene oxide,have great application prospects in the repair and regeneration of vascularized tissues due to their excellent biological properties,good angiogenesis and vascularized bone ability.
