Bhd., 3School of Pharmacy, Faculty of Health & Medical Sciences, Taylor's University, 7 This protocol demonstrates how to isolate human umbilical cord-derived mesenchymal stem cells' small extracellular vesicles (hUC-MSC-sEVs) with a simple lab-scale benchtop setting. The size distribution, protein concentration, sEVs markers, and morphology of isolated hUC-MSC-sEVs are characterized by nanoparticle tracking analysis, BCA protein assay, western blot, and transmission electron microscope, respectively.
