EMT markers are reported to be expressed by CTCs captured from breast cancer patients indicating that factors in blood could aid in the EMT process.32 Plasma is rich in pro-inflammatory cytokines8 that aid in the metastatic process and we found an interesting switch of COLO 205 cells preferentially to the suspended state showing increased expression of E-selectin ligands when treated with human plasma. Here, SELE is linked to breast carcinoma.
