Pro-Angiogenic Bioactive Molecules in Vascular Morphogenesis: Integrating Endothelial Cell Dynamics

Area of Science:

• Developmental Biology
• Cell Biology
• Biomedical Engineering

Background:

• Embryonic development involves complex angiogenesis and arteriogenesis for tissue growth.
• Vessel assembly utilizes diverse morphogenetic mechanisms like budding and intussusception.
• Molecular pathways, particularly the VEGF/VEGFR signaling, govern these processes.

Purpose of the Study:

• To review the diversity of morphogenetic mechanisms in blood vessel assembly.
• To discuss molecular regulation of cell behaviors in angiogenesis, focusing on the VEGFR pathway and HIF-1α.
• To highlight the role of cellular chirality in vascular morphogenesis.

Main Methods:

• Literature review of angiogenesis and arteriogenesis mechanisms.
• Analysis of molecular pathways, including VEGF/VEGFR signaling and HIF-1α.
• Discussion of cellular chirality's impact on endothelial cell organization.

Main Results:

• VEGF/VEGFR signaling is central to vascular morphogenesis, with VEGFR2 playing a key role.
• Cellular chirality influences endothelial cell orientation and migration during angiogenesis.
• Multiple factors, including signaling, mechanical forces, and ECM interactions, affect cellular chirality.

Conclusions:

• Understanding blood vessel morphogenesis is key to developing engineered vascular tissues.
• Cellular chirality is an emerging mechanism critical for organized vascular network formation.
• Further research into molecular control and stabilization mechanisms is ongoing.
