Figure 5. Identification of metastasis subtypes in OS. (A) t-SNE of the mRNA expression profiles of MRGs from the OS samples in the TARGET dataset confirmed the three clusters: A, B and C. (B) Kaplan-Meier curves for the three molecular patterns of OS patients. (C) Heatmap depicted the correlation between the subtypes and different clinicopathological characteristics. (D) Boxplots showed abundance of 23 infiltrating immune cell types.
