描述了胶原偶联的聚乙二醇/聚丙烯酸(PEG/PAA)互穿聚合物网络水凝胶的开发和表征。使用胶原蛋白的定量氨基酸分析和FITC标记来确定水凝胶表面上胶原蛋白的量和分布。通过构象特异性抗体检测偶联的胶原蛋白的生物活性,并且发现其随着与光化学官能化的水凝胶表面反应的胶原蛋白的浓度而变化。基于器官培养模型的伤口愈合测定表明,该生物活性表面支持水凝胶上的上皮伤口闭合,但相对于假伤口的速率降低。将水凝胶植入活兔角膜中表明,上皮细胞迁移受到材料的支持,尽管上皮细胞的迁移速率和形态不正常。该研究的结果将用于指导生物活性水凝胶的优化,并有望用于角膜植入物应用,如角膜高嵌体和人工角膜。© 2008 Wiley Periodicals,Inc.生物医学材料研究杂志,2009年
The development and characterization of collagen‐coupled poly(ethylene glycol)/poly(acrylic acid) (PEG/PAA) interpenetrating polymer network hydrogels is described. Quantitative amino acid analysis and FITC‐labeling of collagen were used to determine the amount and distribution of collagen on the surface of the hydrogels. The bioactivity of the coupled collagen was detected by a conformation‐specific antibody and was found to vary with the concentration of collagen reacted to the photochemically functionalized hydrogel surfaces. A wound healing assay based on an organ culture model demonstrated that this bioactive surface supports epithelial wound closure over the hydrogel but at a decreased rate relative to sham wounds. Implantation of the hydrogel into the corneas of live rabbits demonstrated that epithelial cell migration is supported by the material, although the rate of migration and morphology of the epithelium were not normal. The results from the study will be used as a guide toward the optimization of bioactive hydrogels with promise in corneal implant applications such as a corneal onlay and an artificial cornea. © 2008 Wiley Periodicals, Inc.
