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...

Background:

Angiogenesis, the formation of new blood vessels from existing ones, is vital for wound healing and tissue granulation.
Existing methods for evaluating angiogenesis have limitations, necessitating improved quantitative analysis.
Development of effective angiogenic and anti-angiogenic therapies requires robust assessment models.

Purpose of the Study:

To review novel and existing methods for assessing angiogenesis.
To focus on techniques for the quantification of angiogenesis.
To guide the development of convenient, cost-effective anti-angiogenic treatments.

Main Methods:

Review of various in vitro, in vivo, and in ova models for angiogenesis assessment.
Analysis of established and emerging quantification techniques for angiogenesis.
Examination of non-invasive procedures for angiogenesis measurement.

Main Results:

Different angiogenesis assays offer distinct advantages and limitations.
Animal models are increasingly used for quantitative analysis of angiogenesis.
Efficacy of pro-angiogenic and anti-angiogenic agents is evaluated using diverse models.

Conclusions:

Accurate quantification of angiogenesis is essential for therapeutic development.
Novel non-invasive methods will significantly advance angiogenesis research.
Improved methods will facilitate the creation of well-tolerated, cost-effective anti-angiogenic treatments.
