Graphene and its derivatives are fascinating materials for their extraordinary electrochemical and mechanical properties. In recent decades, many researchers explored their applications in tissue engineering and regenerative medicine. Reduced graphene oxide (rGO) possesses remarkable structural and functional resemblance to graphene, although some residual oxygen-containing groups and defects exist in the structure. Such structure holds great potential since the remnant-oxygenated groups can further be functionalized or modified. Moreover, oxygen-containing groups can improve the dispersion of rGO in organic or aqueous media. Therefore, it is preferable to utilize rGO in the production of composite materials. The rGO composite scaffolds provide favorable extracellular microenvironment and affect the cellular behavior of cultured cells in the peripheral nerve regeneration. On the one hand, rGO impacts on Schwann cells and neurons which are major components of peripheral nerves. On the other hand, rGO-incorporated composite scaffolds promote the neurogenic differentiation of several stem cells, including embryonic stem cells, mesenchymal stem cells, adipose-derived stem cells and neural stem cells. This review will briefly introduce the production and major properties of rGO, and its potential in modulating the cellular behaviors of specific stem cells. Finally, we present its emerging roles in the production of composite scaffolds for nerve tissue engineering.

还原氧化石墨烯对干细胞的影响:外周神经再生的观点

石墨烯及其衍生物因其非凡的电化学和机械性能而成为迷人的材料。近几十年来,许多研究人员探索了它们在组织工程和再生医学中的应用。还原氧化石墨烯(rGO)与石墨烯具有显着的结构和功能相似性,尽管结构中存在一些残留的含氧基团和缺陷。这种结构具有很大的潜力,因为剩余的氧化基团可以进一步被官能化或修饰。此外,含氧基团可以改善rGO在有机或水性介质中的分散。因此,优选在复合材料的生产中使用rGO。rGO复合支架提供了有利的细胞外微环境,并影响培养细胞在周围神经再生中的细胞行为。一方面,rGO对周围神经的主要成分雪旺细胞和神经元产生影响。另一方面,掺入rGO的复合支架促进几种干细胞的神经源性分化,包括胚胎干细胞、间充质干细胞、脂肪干细胞和神经干细胞。本综述将简要介绍 rGO 的产生和主要特性,以及它在调节特定干细胞细胞行为方面的潜力。最后,我们介绍了其在神经组织工程复合支架生产中的新兴作用。rGO 影响周围神经的主要成分雪旺氏细胞和神经元。另一方面,掺入rGO的复合支架促进几种干细胞的神经源性分化,包括胚胎干细胞、间充质干细胞、脂肪干细胞和神经干细胞。本综述将简要介绍 rGO 的产生和主要特性,以及它在调节特定干细胞细胞行为方面的潜力。最后,我们介绍了其在神经组织工程复合支架生产中的新兴作用。rGO 影响周围神经的主要成分雪旺氏细胞和神经元。另一方面,掺入rGO的复合支架促进几种干细胞的神经源性分化,包括胚胎干细胞、间充质干细胞、脂肪干细胞和神经干细胞。本综述将简要介绍 rGO 的产生和主要特性,以及它在调节特定干细胞细胞行为方面的潜力。最后,我们介绍了其在神经组织工程复合支架生产中的新兴作用。本综述将简要介绍 rGO 的产生和主要特性,以及它在调节特定干细胞细胞行为方面的潜力。最后,我们介绍了其在神经组织工程复合支架生产中的新兴作用。本综述将简要介绍 rGO 的产生和主要特性,以及它在调节特定干细胞细胞行为方面的潜力。最后,我们介绍了其在神经组织工程复合支架生产中的新兴作用。
