Fig 1: Isolation and characterization of exosomes from amniotic membrane stem cells (AMSCs). (A) Representative transmission electron microscopic findings of exosomes. (B) Particle size distribution of AMSC exosomes analyzed by a Nanoparticle-Tracking Analysis system. Red line: calibration curve for quantification, blue number: size of each peak. (C) Western blot analysis of CD9-, CD63-, and CD81-positive exosomes in normal conditioned medium (NCM) and exosome-rich conditioned medium (ERCM). (D) Concentrations of growth factors (GFs) and neurotrophic factors (NFs) in NCM (white bars) and ERCM (black bars). KGF: keratinocyte growth factor, EGF: epidermal growth factor, FGF1: fibroblast growth factor 1, TGF–β: transforming growth factor–β, VEGF: vascular endothelial growth factor. * Significantly different from NCM (p < 0.05).
