组织工程化肌腱研究进展

THE RECENT ADVANCES IN THE STUDY OF TISSUE ENGINEERING TENDON

对组织工程化肌腱领域中目前研究的主要成果进行综述，着重阐述了肌腱细胞外基质替代物、肌腱细胞生物学性质及肌腱细胞与细胞外基质材料复合研究中的主要问题。认为，研制适于肌腱细胞生长、粘附和发挥功能的细胞外基质材料；建立生长、增殖可调控的肌腱细胞系；在模拟体内力学条件下，进行肌腱细胞三维培养，将是研究具有特定修复功能的组织工程化肌腱的重要问题。

This paper reviewed the main achievements in the research on tissue engineering tendon, focusing on major problems concerning the substitute for extracellular matrix (ECM) of tendon, biological characteristics of tendon cells, and tendon cells compounding with ECM substitute. It was concluded the important problems in the study of the tissue engineering having specific reparative functions could be: to prepare the ECM materials suitable for the tendon cells to attach, grow, and function; to establish the tendon cell line whose growth, proliferation, and immunological antigenicity could be modulated and controlled, and simulating the mechanical environment of tendon in vivo, to adopt threedimensional tendon cell culture method.
