Association between of ligands and receptors related to the progression of early breast cancer in tumor epithelial and stromal cells

Despite advances in the study of breast cancer (BC), it remains the second leading cause of mortality among women. BC is a heterogeneous system, mainly composed of tumor epithelial cells (TEpCs) and stromal cells (SCs); the interaction through the ligands and their receptors (Rs) plays a major role in BC progression. The aim of the present study was to evaluate the association between ligands, such as osteoprotegerin, tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), receptor activator of nuclear factor kappa B ligand (RANKL), stromal cell-derived factor (SDF)-1, interleukin (IL)-6, macrophage colony stimulating factor, chemokine (C-C motif) ligand-2 (CCL-2), and their Rs in TEpC and spindle-shaped SCs not closely associated with the vasculature.
