Morphological structure identification of exosomes in heat shock, TGF-β1, doxorubicin, acidic, and H/R conditions. (a) After heat shock, TGF-β1, doxorubicin, acidic, and H/R, the morphology of exosomes from HepG2 cell culture supernatants was assessed using TEM. Typical exosomal morphology is indicated by arrows. (b) The particle size distributions of exosomes were displayed. (c) Western blot was adopted to test exosome markers (CD63, CD9, and TSG101) and the endoplasmic reticulum indicator (CNX) in each group.
