VCAM1 and neoplasm: Epithelial tumor cells express epithelial cell adhesion molecule (EpCAM), early pEMT is characterized by lack of EpCAM expression and a CD106+/-/CD51-/CD61- phenotype, late pEMT status is characterized by a CD106+/-/CD51+/CD61- phenotype, and full EMT tumor cells exhibit a CD106+/-/CD51+/CD61+ phenotype 20, 44.
