Protein adsorption, hMSC attachment, and morphological changes on 3D GFs. A Images of bright field (BF), fluorescent (FITC), and merged images reveal FITC-labeled collagen homogeneously adsorbed onto the surface of graphene foams (GFs). B The attachment and viability of FITC-labeled hMSCs were supported by GFs over 14 days. C FITC-labeled hMSCs were cultured in GFs and TCPS control over 7 days. D Quantification of FITC-labeled hMSCs were cultured in GFs and TCPS control over 7 days. E Quantification number of number of whole cell and F aspect ratio. G Quantitatively nuclear morphology and H aspect ratio.
