Figure 1 Identification of exosome from human adipose-derived mesenchymal stem cell and human umbilical cord-derived mesenchymal stem cell. A: Morphology of human adipose-derived mesenchymal stem cell (hADSC) and human umbilical cord-derived mesenchymal stem cell (hUCMSC); B: Analysis of surface markers on hADSCs and hUCMSCs showed high CD105, CD90, and CD73 expression, but negative HLA-DR and CD45 expression; C: Schematic presentation of exosome isolated from hADSC and hUCMSC by differential ultracentrifugation; D: By TEM, purified hADSC exosome (hADSC-Exo) and hUCMSC exosome (hUCMSC-Exo) exhibit cup-like morphologies; E: Nanoparticle analysis of hADSC-Exo and hUCMSC-Exo; F: hADSC-Exo and hUCMSC-Exo express CD63, CD9, CD81 and calnexin is not expressed. hADSC: Human adipose-derived mesenchymal stem cell; hUCMSC: Human umbilical cord-derived mesenchymal stem cell; hADSC-Exo: Human adipose-derived mesenchymal stem cell exosome; hUCMSC-Exo: Human umbilical cord-derived mesenchymal stem cell exosome.
