Regulation of Angiogenesis and Blood Supply01:24

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 Angiogenesis01:10

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...

Summary

Angiogenesis, the formation of new blood vessels, is crucial for fat tissue expansion. Suppressing this process may offer a new strategy for treating obesity.

Area of Science:

  • Physiology
  • Vascular Biology
  • Metabolic Disease

Background:

  • Adipose tissue exhibits significant plasticity, expanding or contracting throughout adult life.
  • Fat mass expansion relies on angiogenesis, the development of new blood vessels.
  • Angiogenesis suppression presents a potential therapeutic avenue for obesity.

Purpose of the Study:

  • To describe methodologies for assessing angiogenesis within adipose tissue.
  • To provide technical procedures for quantifying blood vessel formation in fat depots.

Main Methods:

  • Detailed description of two distinct technical procedures.
  • Focus on the assessment of angiogenesis in adipose tissue samples.

Main Results:
