Background:

The formation of lumens (hollow spaces) by epithelial cells is a fundamental process in both embryonic development and various diseases.
Lumen formation involves a critical interplay between internal fluid or gas pressure and the mechanical forces exerted by surrounding cells.

Purpose of the Study:

To review the mechanical principles governing lumen formation.
To illustrate how mechanical forces balance internal pressure in lumen development.
To discuss the role of advanced mechanics in forming complex, non-spherical lumens.

Main Methods:

Review of existing literature on lumen formation.
Analysis of mechanical forces in epithelial cell structures.
Illustration of biomechanical principles through examples of increasing complexity.

Main Results:

Lumen formation is governed by a balance between internal pressure and cellular mechanical forces.
Complex lumen shapes require overcoming pressure isotropy through nonlinear and active mechanics.
Anisotropic biomechanical structures are essential for forming non-spherical lumens.

Conclusions:

Understanding the mechanical basis of lumen formation is key to addressing developmental and disease processes.
Advanced concepts in nonlinear and active mechanics, along with anisotropic structures, are necessary to explain complex lumen morphogenesis.
Future research should focus on elucidating these intricate biomechanical interactions.
