Podocyte migrasomes and exosomes possess different protein and miRNA profiles. a Schematic illustration of migrasome and exosome purification procedure from cultured HPCs. b TEM images of migrasomes and exosomes. Scale bar, 200 nm. c Western blot analysis of HPCs (cell body), migrasomes, and exosomes using antibodies against Alix and PIGK. d Different miRNA expression profile in migrasomes and exosomes identified by miRNA microarray chip. HPCs, human podocyte cell lines; TEM, transmission electron microscopy.
