Overview of Cell-Matrix Interactions

Overview of Cell-Matrix Interactions

The extracellular matrix or ECM holds cells together to form a tissue and allows the cells within the tissue to communicate. ECM comprises proteins such as fibronectin, collagen, laminin, etc. The most abundant protein in this space is collagen. Collagen fibers are interwoven with carbohydrate-containing protein molecules called proteoglycans. ECM allows cell migration and provides a structural scaffold at cell adhesion that anchors the cell when the extracellular matrix proteins interact with...

Cancer Cell Migration through Invadopodia

Cancer Cell Migration through Invadopodia

Invadosome is a broad category of cell surface structures with proteolytic activity that degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...

Metastasis

Metastasis

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Background:

Parameter estimation in biological models is challenging due to data limitations.
Understanding mechanisms of cell invasion (delay, migration, proliferation) is crucial.

Purpose of the Study:

To develop an efficient computational framework for discovering biological mechanisms.
To quantify uncertainty in the identified mechanisms driving cell invasion.

Main Methods:

Utilizing Gaussian processes (GPs) for mechanism discovery.
Employing bootstrapping for uncertainty quantification.

Demonstrated efficient exploration of functional forms and hypothesis testing.
Provided uncertainty quantification for discovered invasion mechanisms.

Conclusions:

The Gaussian process framework offers an efficient and parallelizable approach for biological mechanism discovery.
The method is broadly applicable to various biological problems beyond cell invasion.
Facilitates hypothesis-driven research in quantitative biology.
