Epithelial-Mesenchymal Transition (EMT) is the trans-differentiation of stationary epithelial cells into motile mesenchymal cells. During EMT, epithelial cells lose their junctions and apical-basal polarity, reorganize their cytoskeleton, undergo a change in the signaling cascade that defines cell shape and reprograms gene expression. Collectively, these changes increase the motility of individual cells and enables the development of an invasive phenotype. At the molecular signaling level, EMT is regulated through several pathways which are triggered by TGF-beta, HGF, EGF, FGF, VEGF, Wnt, SHH, IL6, HIF1 alpha, and other proteins. At the transcription level, SNAI1/Snail, ZEB1/ZEB2 and basic helix-loop-helix transcription factors (bHLH) drive EMT progression. Accumulating evidence has established involvement of EMT in several biological processes including (but not limited to) embryonic and post-embryonic development, tissue regeneration/wound healing, stem cell homeostasis, and in pathophysiology of fibrosis and malignancies.

E Cadherin was detected in immersion fixed D3 mouse embryonic stem cell line using Goat Anti-Human/Mouse E Cadherin Antigen Affinity-purified Polyclonal Antibody (Catalog #AF748) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to cell surfaces. View our protocol for Fluorescent ICC Staining of Stem Cells on Coverslips. |
