组织工程化血管的研究现状

Study on reconstruction of autologous graft vessel by tissue engi- neering

组织工程化血管是在体外构建有生理活性的血管移植物，为心血管外科临床提供新的血管替代物来源。本文介绍近年来血管组织工程所涉及的主要环节，包括种子细胞、支架材料及构建方法新进展及该领域今后的发展方向。

Vascular tissue engineering is in vitro biological activity of vascular graft, which provides new sources of vascular substitutes cardiovascular surgery. We introduced the vascular tissue engineering involving the key elements, including the seed cells, vascular graft and construction progress showed the area＇s future.
