摘要
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 remnantoxygenated 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.
