EPCAM and neoplasm: Tumour cells in particular exhibit downregulation of E specific markers, such as the cad1 epithelial cell adhesion molecule (EpCAM), in the early stage of EMT and conserved expression of keratin (Krt) markers—Krt14, Krt5, or Krt8—in hybrid E/M cells which are completely depleted in the late stages of EMT [13].
