This review covers how vascular endothelial growth factor-A (VEGF-A) drives angiogenesis, the formation of new blood vessels. It also explores abnormal blood vessel formation in diseases and links to other body systems.

Area of Science:

  • Biomedical science
  • Molecular biology
  • Pathology

Background:

  • Angiogenesis is crucial for normal vascular development.
  • Aberrant angiogenesis is implicated in diseases like cancer, wound healing, and inflammation.

Purpose of the Study:

  • To review the angiogenic response mediated by vascular permeability factor/vascular endothelial growth factor (VPF/VEGF) proteins.
  • To focus on VEGF-A as a key angiogenic factor.
  • To classify abnormal blood vessels in pathological angiogenesis.

Main Methods:

  • Literature review of scientific articles on angiogenesis.
  • Analysis of the mechanisms of VEGF-A-induced blood vessel formation.
  • Classification of pathological angiogenesis based on vessel morphology.

Main Results:

  • VEGF-A is a primary driver of angiogenesis.
  • VEGF-A initiates a cascade of events leading to new blood vessel formation.
  • Pathological angiogenesis involves distinct types of abnormal blood vessels.
  • Emerging connections exist between angiogenesis, hemostasis, and the nervous system.

Conclusions:

  • VEGF-A plays a central role in both physiological and pathological angiogenesis.
  • Understanding VEGF-A's mechanisms is key to targeting diseases.
  • Further research is needed to elucidate the interplay between angiogenesis and other systems.
