Developmental Design of Synthetic Bacterial Architectures by Morphogenetic Engineering

Area of Science:

• Synthetic Biology
• Developmental Biology
• Computational Biology

Background:

• Synthetic biology typically focuses on individual cells as chemical factories.
• Engineering complex multicellular forms with predictable shapes remains a significant challenge.

Purpose of the Study:

• To develop a computational framework for engineering multicellular organism shapes.
• To explore developmental processes for creating artificial 3D structures using synthetic biology principles.

Main Methods:

• Utilized the Escherichia coli simulator Gro for in silico multicellular development.
• Modeled cell differentiation, communication via morphogen diffusion, and mechanical interactions.
• Implemented a cell-based genome controlling developmental rules and behaviors.

Main Results:

• Successfully simulated the endogenous emergence of specific multicellular shapes (e.g., L and T shapes).
• Demonstrated control over appendage growth and size through genome parametrization.
• Showcased the potential for creating complex, recursive architectures.

Conclusions:

• Shape engineering is a viable approach for creating artificial multicellular systems with desired forms.
• This method allows for the exploration of novel functional forms through evolutionary developmental processes.
• The framework supports the design of bio-integrated systems for applications in medicine and engineering.
