The vascular microenvironment and its stem cells regulate vascular homeostasis

Area of Science:

• Vascular Biology and Medicine
• Cellular and Molecular Medicine
• Tissue Engineering and Regenerative Medicine

Background:

• The vascular microenvironment is essential for maintaining vascular homeostasis under physiological conditions.
• Alterations in the vascular microenvironment contribute to vascular injury and pathological remodeling in disease states.
• Understanding the intricate components of the vascular microenvironment is key to developing novel therapeutic strategies.

Purpose of the Study:

• To review the structural organization of the vascular microenvironment.
• To examine the role of vascular cells and stem/progenitor cells in regulating vascular function.
• To elucidate the involvement of the vascular microenvironment in cardiovascular diseases.

Main Methods:

• Comprehensive literature review of studies on vascular microenvironment structure and function.
• Analysis of research on cellular and extracellular matrix components within the vascular microenvironment.
• Synthesis of findings related to the impact of microenvironmental alterations on vascular pathology.

Main Results:

• The vascular microenvironment is anatomically divided into endothelial, vascular wall, and perivascular compartments.
• Each compartment contains specific cell populations (e.g., endothelial cells, stem cells) and extracellular matrix elements.
• Dysregulation of these compartments is implicated in diseases like atherosclerosis and vascular inflammation.

Conclusions:

• Targeted modulation of the vascular microenvironment presents a novel therapeutic avenue for diverse diseases.
• Further research into the specific roles of each microenvironmental component can lead to improved disease treatments.
• The vascular microenvironment is a critical determinant of vascular health and disease progression.
