Pushing, pulling, and squeezing our way to understanding mechanotransduction

Area of Science:

• Biophysics
• Cell Biology
• Tissue Engineering

Background:

• Mechanotransduction is traditionally viewed as force-induced molecular changes.
• In vivo mechanical stimuli are complex, arising within multicellular tissues.
• Understanding mechanotransduction requires multi-length scale investigation.

Purpose of the Study:

• To review experimental methods for investigating mechanotransduction across multiple length scales.
• To bridge the gap between molecular-level and tissue-level mechanotransduction studies.
• To guide future research combining diverse techniques.

Main Methods:

• Review of experimental techniques at molecular, cellular, and tissue levels.
• Discussion of methods probing single-molecule force responses.
• Highlighting techniques for cellular mechanical-biochemical activity transduction.
• Examination of approaches for multicellular mechanical stimuli analysis.

Main Results:

• Experimental methods exist to study mechanotransduction at various scales.
• Techniques range from single-molecule force spectroscopy to multicellular tissue analysis.
• A multi-scale approach is crucial for comprehensive understanding.

Conclusions:

• Investigating mechanotransduction requires a multi-length scale perspective.
• Combining techniques across scales will enhance understanding of biological force responses.
• Future research should integrate molecular, cellular, and tissue-level methods.
