简介：

Overview

This article presents a protocol for the implantation of a tissue-engineered vascular graft into the mouse carotid artery using the cuff technique. This method provides a suitable animal model for investigating vascular tissue regeneration mechanisms.

Key Study Components

Area of Science

• Cardiovascular biomaterials
• Regenerative medicine

Background

• Low patency of small-diameter vascular grafts is a significant challenge.
• Bio tubes composed of polymer fiber skeletons and animal extracellular matrix are being developed.
• These bio tubes are currently in phase three clinical trials.

Purpose of Study

• To address the issue of low patency in small-diameter vascular grafts.
• To investigate mechanisms of vascular tissue regeneration.

Methods Used

• Implantation of tissue-engineered vascular grafts.
• Use of the cuff technique in a mouse model.
• Assessment of vascular regeneration.

Main Results

• Successful implantation of the grafts into the carotid artery.
• Demonstration of the potential for vascular tissue regeneration.

Conclusions

• The cuff technique is effective for graft implantation in mice.
• This model can be used for further studies on vascular regeneration.
