01

Overview

Epithelial-mesenchymal transition (EMT) is a biological process in which epithelial cells lose their characteristic polarity and cell-cell adhesion, acquiring migratory and invasive properties typical of mesenchymal cells. EMT plays essential roles in embryonic development, tissue repair, and cancer progression. The reverse process—mesenchymal-to-epithelial transition (MET)—is also critical for normal development, stem cell reprogramming, cancer metastasis colonization at distant sites, and wound healing resolution. Dysregulated induction or failure to resolve EMT contributes to pathological conditions like fibrosis and cancer metastasis. Key inducers include TGF-beta and TNF-alpha, which activate transcriptional regulators like Snail, Slug, and Twist. Targeting EMT pathways represents a therapeutic opportunity for metastatic cancers and fibrotic diseases.
