Epithelial-mesenchymal transition (EMT) is a process by which epithelial cells lose their polarity and cell-cell adhesion and acquire mesenchymal-like properties. Synonyms for EMT include mesenchymal transformation, epithelial-mesenchymal plasticity, and epithelial-mesenchymal shift. The process is typically associated with wound healing and embryonic development, but it is also linked to cancer metastasis, tumor invasion, and drug resistance. A better understanding of the molecular mechanisms underlying EMT could have important implications for the treatment of cancer and other diseases. Therefore, the identification of new synonyms for EMT could facilitate communication and collaboration among researchers in this field.
