대동맥 석회화와 염증의 혈관 평활근 세포 및 이미지의 석회화

Overview

This protocol outlines methods for visualizing and quantifying vascular calcification in cultured primary murine aortic smooth muscle cells and animal aortas. It aims to enhance understanding of the molecular mechanisms underlying vascular disease.

Key Study Components

Area of Science

• Vascular biology
• Cardiovascular disease
• Cellular imaging

Background

• Vascular calcification is a significant factor in cardiovascular disease.
• Understanding calcification mechanisms can aid in disease management.
• Macrophage activity is linked to vascular inflammation and calcification.
• In vitro models are essential for studying these processes.

Purpose of Study

• To visualize aortic vascular calcification ex vivo.
• To model in vivo vascular calcification using cultured cells.
• To assess macrophage inflammation in relation to calcification.

Methods Used

• Induction of calcification in cultured primary vascular smooth muscle cells.
• Quantification of calcification in animal aortas.
• Near-infrared fluorescence imaging for sensitive detection.
• Co-localization of macrophage activity with calcium deposits.

Main Results
