Peptide-conjugated m-GO film promotes osteogenic differentiation of WJ-MSCs. (a) Schematic demonstration of the procedure to differentiate WJ-MSCs into osteogenic lineages on the m-GO and peptide/m-GO film. (b) Alizarin Red staining of WJ-MSCs on the m-GO film before and after conjugate with peptide sequences (PepS1, PepS2, PepS3, and PepS4) after 14 days of osteogenic medium (OM) incubation. All scale bars represent 200 µm.
