Vascular calcification: New insights into endothelial cells

Area of Science:

• Cardiovascular Biology
• Vascular Pathology
• Cellular Biology

Background:

• Vascular calcification is a common pathological basis for vascular disease and a significant risk factor for cardiovascular events.
• Traditionally, vascular calcification is understood to involve processes similar to bone and cartilage development, with vascular smooth muscle cell transformation being a key event.
• However, emerging research suggests a broader cellular involvement.

Purpose of the Study:

• To explore the multifaceted role of endothelial cells in vascular calcification.
• To review recent findings on how endothelial cells contribute to vascular calcification.
• To provide a theoretical foundation for novel clinical strategies in preventing and treating vascular calcification.

Main Methods:

• This review synthesizes current scientific literature on vascular calcification.
• It examines the mechanisms by which endothelial cells participate in this process.
• Key pathways discussed include endothelial-mesenchymal transition, cytokine secretion, extracellular vesicle release, angiogenesis regulation, and hemodynamic influences.

Main Results:

• Endothelial cells actively participate in vascular calcification through various mechanisms.
• These mechanisms include endothelial-mesenchymal transition, secretion of signaling molecules, and release of extracellular vesicles.
• Endothelial cells also influence calcification via regulation of blood vessel formation and responses to blood flow dynamics.

Conclusions:

• Endothelial cells are critical players in the pathogenesis of vascular calcification, beyond the established role of vascular smooth muscle cells.
• Understanding the complex interactions involving endothelial cells offers new therapeutic targets.
• This review provides insights for developing innovative clinical approaches to manage vascular calcification and reduce cardiovascular risk.
