Figure 1 Identification of human umbilical cord-derived mesenchymal stem cells and characterization of exosomes. A: Representative bright-field microscopy image of human umbilical cord-derived mesenchymal stem cells (HUC-MSCs); B: HUC-MSCs identification by flow cytometry phenotyping; C: Representative electron microscopy image of HUC-MSC-derived exosomes; D: Size distribution of exosomes (Exos) determined by nanoparticle tracking analysis; E: Western blot analysis of the surface markers of HUC-MSCs and exosomes. Hypo-Exos: Hypoxia-preconditioned mesenchymal stem cell-derived exosomes; Normo-Exos: Normoxic exosomes; TSG101: Tumor susceptibility gene 101.
