An integrated approach to quantitative modelling in angiogenesis research

Area of Science:

• Biomedical Engineering
• Developmental Biology
• Mathematical Biology

Background:

• Angiogenesis, the formation of new blood vessels, is crucial for development and disease.
• The cornea micropocket assay offers a controlled environment to study angiogenesis.
• Understanding the roles of specific angiogenic factors is vital for therapeutic development.

Purpose of the Study:

• To gain mechanistic insight into the roles of vascular endothelial growth factor A (VEGF-A) and basic fibroblast growth factor (bFGF) in angiogenesis.
• To quantitatively analyze angiogenesis using advanced image processing and mathematical modeling.
• To evaluate the efficacy of the cornea micropocket assay and explore synergistic effects of VEGF-A and bFGF.

Main Methods:

• Utilizing the cornea micropocket assay for controlled angiogenesis experiments.
• Applying image processing and analysis to extract spatiotemporal quantitative data.
• Developing and parametrizing a mathematical model of corneal vasculature evolution.

Main Results:

• Extracted quantitative, spatiotemporally resolved data on angiogenesis from experimental images.
• Developed a mathematical model to simulate corneal vasculature dynamics under VEGF-A and bFGF influence.
• Used experimental data for model calibration and validation.

Conclusions:

• The study provides mechanistic insights into VEGF-A and bFGF actions during angiogenesis.
• The mathematical model aids in assessing the cornea micropocket assay's utility.
• Characterized potential synergistic interactions between VEGF-A and bFGF in regulating blood vessel formation.
