Int J Mol Sci:双组分水凝胶体系可促进外周神经的再生

2017-08-21 MedSci MedSci原创

对于下一代神经导管(NGC),需要新的生物材料和功能化概念来满足周围神经再生(PNR)的临床需求。作为具有生物活性基序的生物聚合物,凝胶肽则有希望满足这一需求,可与含酸酐的低聚物组合,建立了双组分水凝胶体系(cGEL)。首先,通过连续计量和模板方法制造空心cGEL管。导管的特征在于其机械强度,体外和体内降解和生物相容性。然后,将cGEL重新配制成用于建立的NGC的可注射剪切稀释填料,这里是由酪氨酸

对于下一代神经导管(NGC),需要新的生物材料和功能化概念来满足周围神经再生(PNR)的临床需求。作为具有生物活性基序的生物聚合物,凝胶肽则有希望满足这一需求,可与含酸酐的低聚物组合,建立了双组分水凝胶体系(cGEL)。

首先,通过连续计量和模板方法制造空心cGEL管。导管的特征在于其机械强度,体外和体内降解和生物相容性。然后,将cGEL重新配制成用于建立的NGC的可注射剪切稀释填料,这里是由酪氨酸衍生的聚碳酸酯基编织管道。因此,该制剂含有小分子LM11A-31。


评估生物功能化cGEL填料的结构单元整合,机械性能,体外细胞毒性和对人类脂肪组织来源的干细胞的生长允许作用。体外评估促进了填充材料在坐骨神经缺损中的进一步应用。尽管自体神经移植仍然是黄金标准,但是与空导管和原始cGEL相比,功能化cGEL表现优异。

总之,该研究结果表明,具有细胞外基质(ECM)样特征和特异性生化指示的LM11A-31功能化cGEL填料具有很好的支持PNR的潜力。

Biomaterials:热降解水凝胶实现药物按需递送

水凝胶材料近年来在生物医药领域受到了广泛关注,例如作为药物递送载体、组织再生支架、外科手术缝合胶等。负载药物的水凝胶可在体内保持数日乃至数周的持续释放,很大程度上提高了药物的利用度和病人的耐受性,并降低药物毒副作用。如在水凝胶材料中引入酸、酶、光、热等刺激响应元件,则可进一步赋予水凝胶药物载体更加灵活可变的药物控制释放性能。近日,华东师范大学的程义云教授团队研发出一种可在43摄氏度的条件下快速降解
