Epithelial-Mesenchymal Transition (EMT) Markers

Epithelial-Mesenchymal Transition (EMT) is the trans-differentiation of stationary epithelial cells into motile mesenchymal cells. During EMT, epithelial cells lose their junctions and apical-basal polarity, reorganize their cytoskeleton, undergo a change in the signaling cascade that defines cell shape and reprograms gene expression. Collectively, these changes increase the motility of individual cells and enables the development of an invasive phenotype.

CD63: is it pro-metastatic or anti-metastatic?

CD63 is a type II membrane protein belonging to tetraspanin superfamily and it play key roles in the activation of several cellular signaling cascades along with acting as TIMP1 receptor. It is expressed by activated platelets, monocytes, macrophages, granulocytes, T /B cells, and different type of cancer cells. CD63 localizes to endosomes, lysosomes and on the cellular surfaces, and is often considered as a marker for late endosomes as well as for lysosomes.
