Fig. 3From: Magnetic targeting enhances the cutaneous wound healing effects of human mesenchymal stem cell-derived iron oxide exosomesMesenchymal stem cell -derived exosome (MSC-Exo) and MSC-Exo + NP characterization. Morphology of MSC-Exos (a) and MSC-Exos + NPs (b) observed by TEM. The red arrow indicates the membrane. c Western blot analysis of MSC-Exo and MSC-Exo + NP surface marker proteins (Alix and CD9). Size distribution of MSC-Exos (d) and MSC-Exo + NPs (e) determined by NP tracking analysis. f Iron content of MSC-Exos and MSC-Exo + NPs detected by ICP-OES analysis. ***P < 0.001 vs. MSC-ExosBack to article page
