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...

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...

Area of Science:

Vascular Biology
Biomedical Imaging
Zebrafish Models

Background:

Quantifying angiogenesis is crucial for understanding development and disease.
Current methods like microscopy are often time-consuming, costly, and may miss subtle capillaries.
A need exists for a more accessible and accurate angiogenesis quantification technique.

Purpose of the Study:

To develop and validate a simple, motion-based method for visualizing and quantifying angiogenesis.
To demonstrate the method's utility in analyzing the effects of growth factors and inhibitors on blood vessel formation.
To assess the method's applicability in tracing embryonic vasculature development.

Main Methods:

Utilized image analysis software (ImageJ or EVIM) to process video clips of zebrafish caudal fin regeneration.
Calculated frame-to-frame deviations in video stacks to identify pixels exhibiting motion.
Developed a motion-based imaging technique to highlight blood-perfused vessels and quantify angiogenic vasculature.

Main Results:

The motion-based method successfully generated images revealing the entire angiogenic vasculature.
Automatic quantification of newly developed vasculature was achieved.
The method effectively quantified the pro-angiogenic effects of basic fibroblast growth factor and vascular endothelial growth factor, and the inhibitory effect of a specific compound.
Preliminary studies showed potential for tracing vasculature development in zebrafish embryos.

Conclusions:

Motion-based angiogenesis analysis offers a simple, accurate, and efficient method for quantifying blood vessel formation.
This technique overcomes limitations of traditional methods, including cost and detection sensitivity.
The approach holds promise for research in developmental biology, regenerative medicine, and drug discovery involving angiogenesis.
