The prevalence of hybrid/partial EMT/MErT cases (five out of seven) enriched in CSCs (P-cadherin-positive) which are known to colonise or be primed for metastatic spreading [9], also give a new biological meaning to MErT, which should no longer be viewed simply as the expression of a more differentiated state, but also as an epithelial featuring carcinoma-like expression of cells enriched in stemness traits. This evidence concerns the gene CDH3 and carcinoma.
