Green Fluorescent Protein expression achieved with silk-based gene delivery systems. H(SV40)M15HABt and H(SV40)615KHABd showed the highest transfection levels when compare to other silk constructs. Lipofectamine 2000 was used as a positive control, while untransfected hMSCs served as a negative control.
