Cell-matrix's Response to Mechanical Forces

Cell-matrix's Response to Mechanical Forces

In animal cells, the extracellular matrix allows cells within tissues to withstand external stresses and transmits signals from the outside of the cell to the inside. The extracellular matrix is extensive, and its composition varies between different types of tissues. For example, the reticular fibers and ground substance make up the ECM in loose connective tissue, while collagen and bone minerals make up the ECM of bone tissue.
Anchoring junctions mechanically attach a cell to the...

Mechanistic Models: Compartment Models in Individual and Population Analysis

Mechanistic Models: Compartment Models in Individual and Population Analysis

Mechanistic models are utilized in individual analysis using single-source data, but imperfections arise due to data collection errors, preventing perfect prediction of observed data. The mathematical equation involves known values (Xi), observed concentrations (Ci), measurement errors (εi), model parameters (ϕj), and the related function (ƒi) for i number of values. Different least-squares metrics quantify differences between predicted and observed values. The ordinary least squares (OLS)...

Non-equilibrium in the Cell

Non-equilibrium in the Cell

An important concept in studying metabolism and energy is that of chemical equilibrium. Most chemical reactions are reversible. They can proceed in both directions, releasing energy into their environment in one direction, and absorbing it from the environment in the other direction. The same is true for the chemical reactions involved in cell metabolism, such as the breaking down and building up of proteins into and from individual amino acids, respectively. Reactants within a closed system...

Mechanistic Models: Overview of Compartment Models

Mechanistic Models: Overview of Compartment Models

Mechanistic models, a category encompassing both physiological and compartmental modeling, differ from empirical models' approaches to incorporating known factors about the systems being modeled. Empirical models describe data with minimal assumptions, while mechanistic models aim to provide a robust description of available data by specifying assumptions and integrating known factors about the system. Compartmental analysis is a key example of a mechanistic model in pharmacokinetics and...

Background:

Understanding epithelial cell behavior in tissue formation is crucial but challenging experimentally.
Mathematical and computational models offer an alternative to overcome biological experiment limitations.

Purpose of the Study:

To introduce a single-cell-based computational model for simulating epithelial tissue cross-sections.
To investigate the biomechanical properties of cells, cell-cell interactions, and environmental effects on tissue development.

Main Methods:

Developed a single-cell model with sub-cellular elements (plasma membrane, cytoskeleton, nucleus) representing viscoelastic properties.
Modeled cell-cell and cell-environment interactions through segmented cell membranes.
Simulated various cellular phenomena including growth, division, apoptosis, polarization, and tissue morphogenesis.

Main Results:

The model successfully simulates epithelial tissue formation, including monolayer culture, adhesion effects, and extracellular matrix interactions.
It accurately models tissue morphogenesis, tensegrity, and the formation of hollow epithelial acini.
The model allows isolation of biomechanical and communication effects on tissue structure and function.

Conclusions:

The proposed computational model provides a powerful tool for studying epithelial tissue development and morphogenesis.
It enables detailed investigation of how individual cell properties and interactions influence collective tissue behavior.
This 'in silico' approach complements biological experiments for understanding complex tissue structures.
