Figure 2. Differentially expressed genes from exosomes. (A) Exosomes were observed using transmission electron microscopy. Scale bar, 200 nm. (B) Heatmap of Different Gene Expression in exosomes. (C) Volcano plot of Different Gene Expression in exosomes. (D) Consensus clustering matrix for k = 2. (E) Consensus clustering CDF for k = 2–10. (F) Kaplan–Meier survival curves of OS according to two clusters in TCGA cohort. CDF, cumulative distribution function; OS, overall survival; TCGA, The Cancer Genome Atlas.
