Fig. 4From: Identifying biomarkers of breast cancer micrometastatic disease in bone marrow using a patient-derived xenograft mouse modelUnsupervised hierarchical cluster analysis of 13,294 gene transcripts across seven samples of Washington University Human in Mouse (WHIM17) bone marrow (BM) and corresponding primary tumor and metastatic lesion. Specific sample numbers are indicated (see Table 1) and gene expression clusters specifically upregulated in primary tumor, metastasis, and a subset of BM samples are highlightedBack to article page
