摘要: 在高压氮气作用下用溶液喷丝制备了组织工程支架.聚乙二醇/聚对苯二甲酸丁二醇酯(PEGT/PBT)共聚物的氯仿溶液经高压氮气流喷丝,继而沉积成无纺布.为了提高支架的生物相容性,将透明质酸水溶液喷涂到PEGT/PBT丝表面.结果表明,所制备的支架材料的生物相容性良好,细胞外基质透明酸能显著提高无纺布支架的生物相容性.

Abstract: A novel method for solution spray at a high nitrogen pressure was applied in the preparation of tissue engineering scaffolds. The chloroform solution of biodegradable poly(ether ester) poly(ethylene glycol terephthalate)/poly(butylene terephthalate)(PEGT/PBT) was nebulized to give fibers in the nitrogen current and subsequently to accumulate into non-woven scaffolds. At the same time, the hyaluronic acid(HA) aqueous solution was sprayed onto the surface of the resulted fibers to form more biocompatible scaffolds. The implant experiments indicated that these scaffolds were perfect in biocompatibility. HA used as an extracellular matrix improved the biocompatibility of the non-woven scaffolds.

Key words: Solution spray, PEGT/PBT, Tissue engineering, Non-woven scaffold, Biocompatibility
