摘要: 理想的支架材料是组织工程角膜构建的重要条件。目前常用的组织工程角膜支架材料主要包括生物材料、人工材料、复合材料。羊膜、脱细胞角膜基质等生物材料是一种天然结构,具有组织相容性好、含有多种细胞因子、对人体无刺激性等优点,但来源有限,可塑性欠佳。聚羟基乙酸等高分子有机合成材料来源广泛、制作工艺简单、力学性能可控,但在人体代谢过程不尽清楚。复合材料综合了生物材料和有机合成材料的优点,但复合材料的混合比例,生物相容性和其他理化特性还需进一步研究。因此,寻找具有更高生物活性、安全性、透明性的支架材料仍是当前组织工程角膜研究的重点。(国际眼科纵览, 2015, 39:210-215)

Abstract: An ideal scaffold is the basic requirement for constructing a tissue engineering cornea. Currently, the common scaffolds includ biological materials, artificial materials and composite materials. Amnion, acellular corneal stroma and other biological materials belong to natural structures, with good histocompatibility, containing a variety of cytokines, and being non-irritating to body, but with limited sources and poor plasticity. Synthetic materials such as PGA have wide variety of sources, simple fabrication process, and controllable mechanical properties, but the metabolic process in the body is unclear. Composite material combines the advantages of bio- and organic synthetic material, but the mixing ratio of composite materials, biocompatibility and other physical and chemical characteristics need further study. Therefore, searching for a scaffold with higher biological activity, security, and transparency for tissue engineering is still the focus of the current corneal tissue engineering study.  (Int Rev Ophthalmol, 2015, 39:210-215)
