Area of Science:

  • Computational biology
  • Biophysics
  • Tissue engineering

Background:

  • Cell-based models, like the Cellular Potts Model (CPM), are vital for studying tissue formation by simulating cell physical properties and collective behavior.
  • Current methods often rely on manual parameter tuning and visual evaluation, limiting comprehensive analysis of model dynamics.
  • Understanding the link between microscopic cellular processes and macroscopic tissue outcomes requires systematic exploration of model parameter spaces.

Purpose of the Study:

  • To develop and present a protocol and scripts for automating the setup, execution, and evaluation of large-scale parameter sweeps in cell-based models.
  • To facilitate the generation of morphospaces and gain deeper insights into how microscopic factors influence macroscopic tissue properties.
  • To demonstrate the protocol's applicability and versatility across different modeling frameworks.

Main Methods:

  • Development of a protocol for automated parameter sweep execution in cell-based modeling.
  • Creation of a script set to manage simulation setup, running, and evaluation.
  • Demonstration using a Cellular Potts Model of blood vessel formation in CompuCell3D and adaptation to the VirtualLeaf framework.

Main Results:

  • Successful implementation of an automated protocol for large-scale parameter sweeps in cell-based models.
  • Demonstrated efficiency and versatility of the protocol in analyzing complex biological systems.
  • Validation of the protocol's utility in a blood vessel formation model and its adaptability to other platforms.

Conclusions:

  • The automated protocol significantly enhances the ability to explore parameter spaces in cell-based models.
  • This approach provides a robust framework for understanding the relationship between cellular-level behaviors and emergent tissue-level properties.
  • The developed tools are valuable for researchers in computational biology and tissue engineering, enabling more systematic and comprehensive model analysis.
