Serum and exosomal cytokine expression in patients with DCIS, EBC, and MBC. Exosomes were isolated from 250 µL of patients’ sera by serial ultracentrifugation. Cytokines were detected from serum and lysed exosomes by a multiplex assay. (a) Heatmap showing unsupervised hierarchical clustering of samples, generated with Multi-Experiment Viewer (MeV v4.9). (b) Scatter plots show the comparison of serum and exosomal cytokine concentrations in patients with DCIS (n = 9), early breast cancer (n = 17), and metastatic breast cancer (n = 17). The statistical analysis was performed by Mann‐Whitney-U test analysis. p < 0.05 was considered statistically significant. Graphs were generated using GraphPad Prism 5.
