This study developed an agent-based model to simulate intervertebral disc cell behavior, revealing insights into low back pain causes. The model accurately predicts cell death and changes in gene expression under various conditions.

Area of Science:

Biomedical Engineering
Computational Biology
Systems Biology

Background:

Low back pain is a leading cause of global disability, often linked to intervertebral disc (IVD) failure.
Microtrauma accumulation is implicated in IVD failure, but its development is challenging to study in vivo or in vitro.
In silico modeling offers a promising approach to investigate microscale cellular responses to multiple stimuli.

Purpose of the Study:

To introduce and validate a hybrid Agent-based (AB) model for simulating Nucleus Pulposus (NP) cell behavior in a 3D multifactorial biochemical environment.
To investigate cellular responses, including mRNA expression and cell viability, under various simulated conditions relevant to IVD degeneration.
To provide a computational tool for understanding the complex factors contributing to IVD microtrauma and failure.

Main Methods:

Developed a hybrid Agent-based (AB) model integrating systems biology network modeling.
Mathematically modeled NP cell behavior based on existing experimental data.
Simulated cellular activity, including mRNA expression (Aggrecan, Collagen I, Collagen II, MMP-3, ADAMTS) and cell viability, under inflamed and non-inflamed conditions.
Validated model predictions against independent experimental data.

Main Results:

The model accurately reproduced cell death within 3 days under glucose deprivation.
A 50% decrease in cell viability was predicted after 7 days in an acidic environment.
Simulated non-inflamed cells showed a quantifiable catabolic shift in an adverse environment.
Model predictions for inflamed cells offer new explanations for experimental findings.

Conclusions:

The developed AB model is a valuable tool for simulating NP cell behavior and understanding IVD degeneration.
The model successfully integrates multifactorial influences on cellular activity, providing mechanistic insights.
Computational modeling can elucidate complex biological processes and guide future experimental research in IVD disorders.
