Cell-cell adhesion interface: orthogonal and parallel forces from contraction, protrusion, and retraction

Area of Science:

• Cell Biology
• Biophysics
• Tissue Engineering

Background:

• The epithelial lateral membrane integrates intercellular signals, influencing epithelial tissue properties.
• Mechanical forces applied to cell-cell interfaces modulate adhesion strength and intercellular dynamics.
• The precise relationship between mechanical force and epithelial cell behavior remains incompletely understood.

Purpose of the Study:

• To investigate the role and application of cellular forces at the epithelial cell-cell adhesion interface.
• To provide an overview of the current understanding of mechanical force effects on epithelial tissues.
• To highlight the complexity of mechanotransduction in epithelial tissues.

Main Methods:

• This commentary synthesizes existing research and theoretical frameworks.
• It involves a review of studies investigating mechanical forces at cell-cell junctions.
• Analysis of how force application impacts adhesion and signaling pathways.

Main Results:

• Mechanical forces significantly influence the strength and stability of epithelial cell adhesion.
• Intercellular forces are critical determinants of epithelial tissue emergent properties.
• The interplay between mechanical cues and cellular responses is complex and multifaceted.

Conclusions:

• Understanding cellular forces at the epithelial adhesion interface is key to deciphering tissue development and function.
• Further research is needed to fully elucidate the mechanisms by which mechanical forces regulate epithelial behavior.
• Targeting cell-cell adhesion mechanics may offer novel therapeutic strategies for epithelial-related diseases.
