a MTT assay after incubation of CS/Gn scaffolds and 0.25% GO/CS/Gn scaffolds with media for 48 h. The asterisk indicates a significant increase versus control, and the pound sign indicates a significant decrease versus control (p < 0.05). b, c Expression of osteogenic-related genes (RUNX2, ALP, COL-1, and OC) in mMSCs cultured on CS/Gn scaffolds and 0.25% GO/CS/Gn scaffolds for 7 and 14 days measured by quantitative RT-PCR.
