The epithelial-mesenchymal transition (EMT) describes the global process by which
stationary epithelial cells undergo phenotypic changes, including the loss of
cell-cell adhesion and apical-basal polarity, and acquire mesenchymal
characteristics that confer migratory capacity. EMT and its converse, MET
(mesenchymal-epithelial transition), are integral stages of many physiologic
processes and, as such, are tightly coordinated by a host of molecular
regulators. Converging lines of evidence have identified EMT as a component of
cutaneous wound healing, during which otherwise stationary keratinocytes (the
resident skin epithelial cells) migrate across the wound bed to restore the
epidermal barrier. Moreover, EMT plays a role in the development of scarring and
fibrosis, as the matrix-producing myofibroblasts arise from cells of the
epithelial lineage in response to injury but are pathologically sustained instead
of undergoing MET or apoptosis. In this review, we summarize the role of EMT in
physiologic repair and pathologic fibrosis of tissues and organs. We conclude
that further investigation into the contribution of EMT to the faulty repair of
fibrotic wounds might identify components of EMT signaling as common therapeutic
targets for impaired healing in many tissues. Graphical Abstract Model for
injury-triggered EMT activation in physiologic wound repair (left) and fibrotic
wound healing (right).
