Fig. 6

The effects of 3D graphene foams (GFs) on the adhesion and osteogenic differentiation of human mesenchymal stem cells (hMSCs). (a - c) The SEM images of hMSCs cultured on 3D GFs for 4 days. The yellow arrows represent formed protrusions up to 100 mm in length that extended from small cell bodies (black arrows). (d) Immunofluorescence images of hMSCs cultured on TCPS and 3D GFs for 7 days. (e) The average cell number was quantified from Fig. 6d. (f) Immunofluorescence images stained with osteogenic markers, Osteocalcin and Osteopontin, for hMSCs cultured on TCPS and GF for 7 days. Scale bar = 50 μm.
