Novel Stromal Biomarkers in Human Breast Cancer Tissues Provide Evidence for the More Malignant Phenotype of Estrogen Receptor-Negative Tumors

<table>2DE: two-dimensional gel electrophoresis (2DE) of epithelial cells (Epi), myofibroblasts (Myo), leukocytes (leuk), and endothelial cells (Endo) proteins separated from estrogen receptor-positive and estrogen receptor-negative breast cancer cells using antibody-bound magnetic beads. First dimension was performed on a pH 4 to 7 isoelectric focusing gels and the second dimension was done utilizing 10% polyacrylamide gels. Gels were stained by Sypro Ruby. Arrows point to identified proteins spots.</table>
