Characterisation of exosomes derived from EPSC. EPSC-Exos were isolated and purified from EPSC supernatant using high-speed centrifugation. a Identification of the main morphological characteristics of EPSC-Exos by transmission electron microscopy images. Scale bar = 100 nm. b RNA expression profiles of EPSC-Exos by Genechip analysis. c The markers of exosomes are detected using western blot assay, and the cell-free medium was added as a control. EGF, epidermal stem cells; EPSC-Exos, epidermal stem cell-derived exosomes
