Method & Evidence

AimTo investigate the potential of graphene oxide/poly(methyl methacrylate) (GO/PMMA) composites to enhance osteogenic differentiation of human primary mesenchymal stem and progenitor cells for bone tissue engineering applications.
MethodExperimental investigation and cell culture analysis.
ProcedureGO/PMMA composite bone cements were fabricated with varying GO concentrations and structures. Human primary mesenchymal stem and progenitor cells were cultured on these scaffolds, both with and without an osteogenic differentiation medium. Osteogenic differentiation was assessed by analyzing three key markers: alkaline phosphatase, secreted protein acidic and rich in cysteine, and bone morphogenetic protein-2.
ContextBiomaterials and tissue engineering, specifically bone regeneration.
