The rat aortic ring model of angiogenesis

Area of Science:

• Vascular Biology
• Cell Culture Techniques

Background:

• Angiogenesis, the formation of new blood vessels, is crucial for development and disease.
• The rat aorta ring assay is a well-established model for studying angiogenesis.

Purpose of the Study:

• To provide detailed protocols for preparing and analyzing rat aorta angiogenic cultures.
• To highlight the utility of this assay in basic and applied angiogenesis research.

Main Methods:

• Aortic rings are embedded in extracellular matrix gels.
• Vascular outgrowths are cultured and monitored using inverted microscopy.
• Angiogenic response is quantified by vessel counting or image analysis.

Main Results:

• The assay allows for the generation and monitoring of vascular outgrowths from aortic rings.
• Quantitative measurements of angiogenesis can be obtained through vessel counting or image analysis.

Conclusions:

• Rat aorta ring cultures are a versatile tool for investigating the molecular mechanisms of angiogenesis.
• This assay is effective for evaluating the efficacy of angiogenesis stimulators and inhibitors.
