Characterization of DPSC-Exo and DPSC-Exo/CS. (A) Representative western blots showing exosome markers (CD9, HSP70, and TSG101) and a cytosolic marker (β-tubulin) of DPSC-Exo and DPSC conditioned media. (B) TEM images of DPSC-Exo morphology. Scale bar = 100 nm. (C) Representation of particle size analysed using NTA. (D) Flow cytometry analysis of CD63 and CD81 expression on DPSC-Exo. (E) Synesis process and schematic illustration of CS hydrogel. (F) The release curves of DPSC-Exo from the CS hydrogel.
