Quantifying the Epithelial-to-Mesenchymal Transition (EMT) from Bench to Bedside

Area of Science:

• Oncology
• Cell Biology
• Cancer Metastasis

Background:

• Epithelial-to-mesenchymal transition (EMT) and its reversal (MET) are key to cancer metastasis.
• Diverse EMT states exist, influencing tumor progression and patient outcomes.
• Current clinical practice rarely defines EMT status for prognosis or treatment.

Purpose of the Study:

• To review advancements in translating EMT biology research from the lab to clinical application.
• To highlight the importance of identifying and quantifying EMT states in patient tumors.
• To guide the development of diagnostic tools for EMT detection in cancer.

Main Methods:

• Review of established techniques: immunofluorescence staining, flow cytometry.
• Discussion of advanced methods: single-cell sequencing, multiplexed tumor mapping.
• Emphasis on combining multiple methods and markers for comprehensive EMT assessment.

Main Results:

• EMT spectrum encompasses various states impacting tumor progression.
• Quantifying EMT states is essential for patient tumor scoring and prognosis.
• Current diagnostic approaches for EMT are not routinely implemented.

Conclusions:

• Translating EMT research into clinical practice is progressing.
• Developing robust diagnostic tools requires integrating multiple detection methods.
• Accurate EMT detection and quantification can significantly aid clinical decision-making for cancer patients.
