The epithelial-mesenchymal transition and the cytoskeleton in bioengineered systems

Area of Science:

• Cell Biology
• Bioengineering
• Biophysics

Background:

• Epithelial-mesenchymal transition (EMT) involves significant changes in cell morphology, cytoskeleton, and extracellular matrix interactions.
• These cellular changes are crucial for cell migration, invasion, and tissue remodeling, particularly in cancer progression.

Purpose of the Study:

• To review recent bioengineering approaches for studying EMT and associated cytoskeleton dynamics.
• To explore how physical microenvironments and advanced imaging techniques elucidate EMT mechanisms.

Main Methods:

• Review of bioengineering techniques applied to study cell-matrix interactions during EMT.
• Analysis of studies focusing on actin and vimentin roles in cell shape and invasion.
• Examination of topographical patterning and 3D matrix invasion models.

Main Results:

• Bioengineering tools allow for controlled physical microenvironments and high-resolution spatiotemporal measurements of EMT.
• Vimentin's role in cell mechanics and confined environments is better understood.
• Multicellular behaviors, leader cell dynamics, and matrix remodeling during EMT are elucidated.

Conclusions:

• Advanced bioengineering strategies provide novel insights into EMT and cytoskeleton function.
• Understanding EMT mechanics is critical for developing new cancer therapies.
• Future research should focus on integrating these technologies to address outstanding questions in cancer progression.
