hUC-MSC-Exos inhibit chemokine production in keratinocytes. A Images of hUC-MSC-Exos captured using a transmission electron microscope; black arrows indicate exosomes. B Nanoparticle tracking analysis using Particle Metrix reveals the size and concentration of hUC-MSC-Exos. C Western blot analysis of the exosome marker proteins, CD63 and TSG101. Full-length blots are presented in Supplementary Figure. D qRT-PCR analysis of chemokine mRNA expression in HaCaT cells treated with TNF-α/IFN-γ (10 ng/mL) or hUC-MSC-Exos (20 μg/mL) for 48 h
