Characteristics of exosomes derived from SGC-7901 and SGC-7901/5-FU GC cells. a The transmission electron micrograph showed round-shaped vesicles with bilayer membranes ranging from 30 nm to 180 nm in diameter released by SGC-7901 (S-Exo) and SGC-7901/5-FU (R-Exo) cells. Scale bar = 500 nm and 200 nm, respectively. b Dynamic light scattering analysis (DLS) indicated that the dominant size of S- and R-Exo was about 120 nm. c The positive markers of exosomes, CD63 and HSP70, were detected in S- and R-Exo by Western blot
