Physical control of tissue morphogenesis across scales

Area of Science:

• Developmental Biology
• Biophysics
• Cellular Biology

Background:

• Embryonic development involves intricate tissue and organ shaping.
• Genetic information dictates form, but physical processes execute it in 3D space.
• Morphogenesis is guided by emergent physical behaviors at supracellular scales.

Purpose of the Study:

• To review physical quantities spatiotemporally tuned at supracellular scales.
• To connect these physical quantities to cellular and molecular mechanisms.
• To understand the physical basis of embryonic tissue sculpting.

Main Methods:

• Literature review of developmental biology and biophysics studies.
• Analysis of supracellular physical quantities in embryonic development.
• Integration of findings with cellular and molecular control mechanisms.

Main Results:

• Identified key physical quantities (e.g., tension, pressure, viscosity) influencing morphogenesis.
• Highlighted the emergent nature of physical forces from cellular behaviors.
• Established links between physical parameters and genetic/molecular regulation.

Conclusions:

• Physical processes are crucial for embryonic morphogenesis, operating at supracellular scales.
• Understanding these physical quantities and their regulation is key to deciphering developmental processes.
• This review provides a framework for studying the biophysics of tissue development.
