Characterization of Pt-ExoshpMSCs and Pt-ExosU251−MG. A Representative TEM image of ExoshpMSCs, Pt-ExoshpMSCs, ExosU251−MG and Pt-ExosU251−MG. Exosomes were negatively stained with phosphotungstic acid to ease imaging by a transmission electron microscopy B HAADF-STEM images of Pt-ExosB16−F10 and EDS spectrum of the red line marked area. C Western blots of exosome-specific biomarkers CD9 and CD81 of exosomes from hpMSC and U251-MG cells both in the presence and in the absence of PtNPs. D Particle size analysis of non-loaded and Pt-loaded ExoshpMSCs and ExosU251−MG obtained by NTA
