Summary
We introduce a new agent-based model, the biological lattice-gas cellular automaton (BIO-LGCA), to better simulate collective cell migration. This model accurately captures cell behaviors crucial for understanding tissue development and disease.
Area of Science:
- Computational Biology
- Biophysics
- Multicellular Systems
Background:
- Collective cell migration is vital for biological development, regeneration, and diseases.
- Classical on-lattice models (cellular automata) struggle to accurately represent collective migration dynamics.
- Existing models lack the ability to incorporate individual cell velocities and experimentally derived interaction rules.
Purpose of the Study:
- To introduce a novel on-lattice agent-based modeling framework, the biological lattice-gas cellular automaton (BIO-LGCA).
- To overcome the limitations of classical cellular automata in simulating collective cell migration.
- To provide a modular and experimentally-grounded approach for studying complex multicellular behaviors.
Main Methods:
- Developed the BIO-LGCA model with synchronous time updates and explicit individual cell velocities.
- Introduced elementary BIO-LGCA models for fundamental cell interactions (adhesion, alignment).
- Applied mathematical mean-field analysis to specific BIO-LGCA models to explain emergent collective behaviors.
Main Results:
- Demonstrated the prediction of cluster formation in adhesively interacting cells using BIO-LGCA.
- Analyzed a novel BIO-LGCA model combining adhesion and alignment to explain breast cancer cell invasion plasticity.
- Showcased the modularity of BIO-LGCA for combining different cell interaction rules.
Conclusions:
- BIO-LGCA offers a more accurate and flexible approach to modeling collective cell migration compared to classical cellular automata.
- The framework allows for the derivation of interaction rules from experimental data or biophysical laws.
- BIO-LGCA provides insights into complex phenomena like cancer cell invasion and tissue development.

01:19Cell Migration
5.6K
Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and regeneration, immune response, and metastasis. Cells migrate in response to chemical or mechanical signals generated by specific organs or tissues. The overall mechanism includes three steps - polarization, protrusion, and release. Polarization involves the formation of a distinct cell front and rear, which determines the direction of movement.

Cell migration, the process by which cells move from one location to another, is essential for the proper development and viability of organisms throughout their life. When cells are not able to migrate properly to their ordained locations, various disorders may occur. For example, disruption in cell migration causes chronic inflammatory diseases such as arthritis.

01:21Chemotaxis and Direction of Cell Migration
3.9K
Cells can detect chemical cues in their environment and reorganize the cytoskeleton to migrate toward them or away from them. This directional migration, called chemotaxis, is essential during embryogenesis and development, immune response, tissue repair and regeneration, and reproduction. These chemical cues can either attract or repel the cell's movement. For example, axon development is determined by a combination of chemoattractants and chemorepellents that direct the growing axon...

01:32Cytoskeletal Coordination in Cell Migration
5.1K
A migrating cell changes its shape during the cyclic events of attachment and detachment from the substratum and repositions the cell organelles correspondingly. These complex events are orchestrated by the dynamic cytoskeletal network comprising actin filaments, intermediate filaments, and microtubules. Cytoskeletal crosstalk — the direct and indirect communication between the different components — is crucial for this coordination. Direct communication involves various linker...

5.9K
Actin is a family of globular proteins that are highly abundant in eukaryotic cells. It makes up approximately 1-5% of total cell protein concentration. Actin monomers polymerize to form a complex network of polarized filaments, the actin cytoskeleton, that plays a crucial role in many cellular processes, including cell motility, division, endocytosis, and metastasis of cancer cells.

01:16Cell Motility through Blebbing
2.2K
Blebs are a type of membrane protrusion formed by the internal hydrostatic pressure of the cytoplasm. Blebs are observed in several cell types, including fibroblasts, immune cells, and single-celled organisms like the amoeba. The primary function of blebs is cell locomotion and apoptosis, but they are also found during necrosis and cell division. The life cycle of a bleb comprises an initiation phase followed by the expansion and retraction phases.
