Summary
Somatic cells exhibit plasticity, with epithelial and endothelial cells undergoing epithelial-mesenchymal transition (EMT). This perspective proposes classifying EMT into three types based on context and plasticity biomarkers for consistent study.
Area of Science:
- Cell biology
- Developmental biology
- Biochemistry
Background:
- Somatic cells possess plasticity, enabling phenotype changes.
- Epithelial-mesenchymal transition (EMT) demonstrates cell plasticity, particularly in epithelial and endothelial cells.
- Current literature lacks standardized criteria for identifying EMT events.
Purpose of the Study:
- To address the uncertainty in EMT identification across studies.
- To propose a framework for classifying EMT based on context and biomarkers.
- To enhance the consistency and reproducibility of EMT research.
Main Methods:
- Review of existing literature on cell plasticity and EMT.
- Analysis of contextual factors influencing EMT.
- Identification and evaluation of plasticity biomarkers associated with EMT.
Main Results:
- EMT is a complex process with potential for at least three distinct types.
- Context-dependent changes in plasticity biomarkers are key identifiers of EMT.
- A unified set of criteria can improve the reliability of studying EMT.
Conclusions:
- Standardizing EMT criteria is crucial for consistent research.
- Recognizing different EMT types aids in understanding cell plasticity.
- This framework facilitates accurate identification of epithelial and endothelial cells transitioning to a motile phenotype.

Metastasis
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Overview of Cell-Matrix Interactions
The extracellular matrix or ECM holds cells together to form a tissue and allows the cells within the tissue to communicate. ECM comprises proteins such as fibronectin, collagen, laminin, etc. The most abundant protein in this space is collagen. Collagen fibers are interwoven with carbohydrate-containing protein molecules called proteoglycans. ECM allows cell migration and provides a structural scaffold at cell adhesion that anchors the cell when the extracellular matrix proteins interact with...
Cadherins in Tissue Organization
The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.
