Hydrostatic pressure as a driver of cell and tissue morphogenesis

Area of Science:

• Developmental biology
• Biophysics
• Cell biology

Background:

• Morphogenesis, the development of tissue structure, traditionally emphasizes actomyosin-driven contraction.
• Emerging evidence highlights the significant role of fluid pressure in driving tissue deformations.
• Understanding these mechanical forces is crucial for comprehending developmental processes.

Purpose of the Study:

• To review the generation and mechanical roles of hydrostatic pressure at cellular and tissue levels.
• To highlight the contribution of fluid-filled lumens and extracellular matrix components to morphogenetic pressure.
• To discuss the interplay between extracellular pressures and tissue remodeling during development.

Main Methods:

• Literature review of studies on tissue morphogenesis and mechanical forces.
• Analysis of findings related to hydrostatic pressure generation and effects.
• Synthesis of research on extracellular matrix and fluid pressure interactions.

Main Results:

• Hydrostatic pressure, from lumens and extracellular matrix, is a key driver of tissue morphogenesis.
• Fluid pressure can induce significant tissue deformations necessary for development.
• Mechanochemical feedbacks between pressure and tissue behavior are vital for remodeling.

Conclusions:

• Fluid pressure is a critical, often underappreciated, force in morphogenesis.
• Further research into pressure-driven mechanisms will reveal new principles of tissue organization.
• Integrating pressure dynamics into developmental models is essential for a complete understanding.
