模拟细胞外基质蛋白质性质的合成底物在为组织工程应用设计的系统中具有重要的应用前景。在这份报告中,我们设计了一种合成的聚合物基板,旨在模仿胶原蛋白的化学,机械和拓扑特征。我们发现,弹性体聚(酯酰胺)基板改性与复制模塑纳米地形功能增强初始附着,扩散和粘附的原代大鼠肝细胞。此外,在纳米形貌基质上培养的肝细胞也显示出白蛋白分泌和尿素合成减少,这表明肝细胞粘附性强。这些结果表明,这些工程化的底物可以作为合成胶原类似物用于体外细胞培养。
Synthetic substrates that mimic the properties of extracellular matrix proteins hold significant promise for use in systems designed for tissue engineering applications. In this report, we designed a synthetic polymeric substrate that is intended to mimic chemical, mechanical, and topological characteristics of collagen. We found that elastomeric poly(ester amide) substrates modified with replica-molded nanotopographic features enhanced initial attachment, spreading, and adhesion of primary rat hepatocytes. Further, hepatocytes cultured on nanotopographic substrates also demonstrated reduced albumin secretion and urea synthesis, which is indicative of strongly adherent hepatocytes. These results suggest that these engineered substrates can function as synthetic collagen analogs for in vitro cell culture.
