Modular microenvironment components reproduce vascular dynamics de novo in a multi-scale agent-based model

Area of Science:

• Computational Biology
• Systems Biology
• Bioengineering

Background:

• Cells interact dynamically with their microenvironment, which also adapts to cellular activity.
• Understanding the interplay between cellular behavior and vascular networks is crucial for biological and medical research.

Purpose of the Study:

• To investigate the impact of vascular structure and function on emergent cell population behavior using an agent-based model (ABM).
• To explore the bidirectional relationship between cells and vasculature.
• To demonstrate the influence of vascular architecture on environmental heterogeneity and cell population dynamics.

Main Methods:

• Development and application of a versatile agent-based model (ABM) capable of simulating complex vascular architectures and hemodynamics.
• Integration of various cell agents, subcellular modules, and microenvironment components.
• Analysis of the non-linear relationships between vascular function and cell population behavior over time.

Main Results:

• The ABM successfully highlights the bilateral relationship between cells and vasculature.
• Vascular structure significantly affects environmental heterogeneity.
• Vascular function exhibits non-linear, non-intuitive effects on cell population behavior.

Conclusions:

• The developed ABM provides a powerful tool for characterizing in vitro and in vivo studies.
• The model has broad applications in basic science, synthetic biology, and translational medicine.
• The study emphasizes the critical role of vascular dynamics in shaping cellular environments and behaviors.
