Developmental Mechanism - Epithelial Mesenchymal Transition
Introduction
Epithelial cells (organised cellular layer) which loose their organisation and migrate/proliferate as a mesenchymal cells (disorganised cellular layers) are said to have undergone an Epithelial Mesenchymal Transition (EMT).
Mesenchymal cells, connective tissue-like, that have undergone this process may at a later time and under specific signaling can undergo the opposite process, mesenchyme to epithelia. In development, this process can be repeated several times during tissue differentiation.
This process is also studied in carcinogenesis (oncogenesis) or cancer development, where part of this process can be the transformation of an epithelial cell into a mesenchymal cell.[1]
