The main role of the scaffold materials is to enable cells to survive in the scaffold binding as while as to further promote their proliferation and differentiation ability. For mesenchymal stem cell, the scaffold could provide an environment for them to maintain their phenotype, and synthesize all necessary molecules and proteins. Generally, scaffold materials for stem cell need to possess basic characteristics such as high porosity, large surface area, surface rigidity and biodeg-radability. Thus, the two-dimensional Graphene Oxide (GO) with oxygen-containing functional groups may be suitable scaffold materials for mesenchymal stem cell culture. In this study, the effect of GO on the value-added differentiation activity of mesenchymal stem cell was systematically investigated. It was found that low concentration of GO and sufficient concentration of umbilical cord mesenchymal stem cells are suitable for the second Co-culture. Furthermore, the addition of hyaluronic acid will make this culture more evenly distributed. The adsorption of GO on umbilical cord mesenchymal stem cells can also make the two closely linked, which avoids the impact of animal joint activities on cells.
