Characterization of serum-derived exosomes of NSCLC. a. Exosomes (black arrows) isolated from NSCLC patients were observed under electron microscopy with 50–150 nm in diameter (bar = 100 nm). b. Size distribution of exosomes measured by NTA (mean value 121.4 nm). c Exosomes-enriched protein CD63/TSG101 and protein PD-L1 were analyzed by western blotting among NSCLC patients and healthy controls
