Therapeutic angiogenesis aims to treat vascular disease by promoting new blood vessel growth. This review explores how vascular endothelial growth factor-A (VEGF) and Notch signaling regulate sprouting angiogenesis and contrasts it with intussusception.
Area of Science:
- Cardiovascular Biology
- Molecular Medicine
- Regenerative Medicine
Background:
- Therapeutic angiogenesis offers a promising strategy for treating peripheral and coronary artery disease.
- Vascular endothelial growth factor-A (VEGF) is a key regulator of blood vessel formation.
- The VEGF and Notch signaling pathways are crucial for sprouting angiogenesis.
Purpose of the Study:
- To review the role of VEGF dose in inducing normal or aberrant angiogenesis.
- To elucidate the molecular regulation of sprouting angiogenesis by Notch signaling.
- To compare sprouting angiogenesis with intussusception in the context of therapeutic angiogenesis.
Main Methods:
- Literature review of existing studies on angiogenesis.
- Analysis of molecular mechanisms regulating VEGF and Notch signaling.
- Comparative review of sprouting and intussusception angiogenesis.
Main Results:
- VEGF dose critically influences the type of angiogenesis induced.
- Notch signaling precisely controls the morphogenic events in sprouting angiogenesis.
- Intussusception's role and regulation in therapeutic angiogenesis remain less understood.
Conclusions:
- Understanding VEGF dose-dependency and Notch signaling is vital for effective therapeutic angiogenesis.
- Further research is needed to explore the mechanisms and therapeutic potential of intussusception.
