Mechanism of Angiogenesis

Mechanism of Angiogenesis

Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...

Regulation of Angiogenesis and Blood Supply

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...

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...

Area of Science:

Computational biology
Biomedical engineering
Mathematical modeling

Background:

Angiogenesis, the formation of new blood vessels, is crucial for tumor growth and is typically modeled using continuous equations.
Representing discrete vessel structures within a continuous modeling framework presents significant challenges.
Existing models struggle to capture the dynamic and discrete nature of blood vessel development.

Purpose of the Study:

To introduce a novel Convected Element Method (CEM) for simulating tumor-induced angiogenesis.
To address the limitations of continuous models in representing discrete blood vessel formation.
To develop a computational tool for understanding vascular network development in tumors.

Main Methods:

Developed a hybrid continuous/discrete Convected Element Method (CEM).
CEM utilizes lattice-free tracking of blood vessel tips to define discrete vessel elements.
The method employs evolving grids to simulate the transport of biological and chemical factors.

Main Results:

CEM successfully simulates the formation of functional vascular structures.
Demonstrated the method's capability in modeling vessel growth and tumor response under various conditions.
Initial simulations show qualitatively reasonable vascular development, including nutrient delivery and branching inhibition.

Conclusions:

The Convected Element Method (CEM) offers a promising approach for simulating angiogenesis.
CEM can qualitatively predict the development of biologically plausible vascular networks.
Further research aims to generalize CEM for quantitative predictions in cancer research.
