Background:

Epithelial sheets form 3D structures through cell shape changes and rearrangements during development.
Two-dimensional vertex models approximate cells as polygons but are limited in capturing 3D morphogenesis.
Understanding the mechanical forces in epithelial folding is crucial for developmental biology.

Purpose of the Study:

To adapt existing 2D vertex models for simulating three-dimensional epithelial morphogenesis.
To provide a computational framework for studying the formation of complex 3D shapes from cell sheets.
To facilitate hypothesis testing regarding mechanical forces in developmental processes.

Main Methods:

Embedding a classical 2D vertex model into a three-dimensional space.
Developing algorithmic and computational approaches for the 3D vertex model.
Analyzing biophysical aspects of cell rearrangements and shape changes in 3D.

Main Results:

Successfully adapted the 2D vertex model to a 3D context.
Demonstrated the construction of complex 3D shapes from simple cell sheets.
Presented a model with potential applications in studying various morphogenetic processes.

Conclusions:

The 3D vertex model offers a novel approach to studying epithelial morphogenesis.
This model can be used to investigate the mechanical underpinnings of development.
The framework is valuable for formulating and testing hypotheses in developmental biology and biophysics.
