The<unk>  (EMT) is a process by which<unk>  cells lose their cell polarity and cell–cell adhesion, and gain migratory and invasive properties to become<unk>  stem cells; these are multipotent stromal cells that can differentiate into a variety of cell types. EMT is essential for numerous developmental processes including mesoderm formation and neural tube formation. EMT has also been shown to occur in wound healing, in organ fibrosis and in the initiation of metastasis in cancer progression.
