Hemangiosarcoma is distinguishable from both non-malignant and other malignant tumors. (A). Hierarchical clustering of tumor samples or non-malignant lesions (hematoma) from golden retrievers. Tumor samples were from osteosarcoma cell lines (OSCA), primary leukemia (ALL-Acute lymphoblastic leukemia or CLL-Chronic lymphocytic leukemia) or non-Hodgkin lymphoma (diffuse large B-cell lymphoma, marginal zone lymphoma, or T-zone lymphoma) cells, or hemangiosarcoma cell lines (HSA). Hierarchical clustering was done using the restricted probe list from Table S2. (B) Principal component analysis (PCA) of tumor samples and non-malignant lesions described in (A), except analysis was done using all data points.
