Self-assembled peptide nanofibers are versatile materials providing suitable platforms for regenerative medicine applications. This chapter describes the use of peptide nanofibers as extracellular matrix mimetic scaffolds for two-dimensional (2D) and three-dimensional (3D) multipotent stromal cell culture systems and procedures for in vitro experiments using these scaffolds. Preparation of 2D and 3D peptide nanofiber scaffolds and cell culturing procedures are presented as part of in vitro experiments including cell adhesion, viability, and spreading analysis. Analysis of cellular differentiation on peptide nanofiber scaffolds is described through immunocytochemistry, qRT-PCR, and other biochemical experiments towards osteogenic and chondrogenic lineage.
自组装肽纳米纤维是多功能材料,为再生医学应用提供了合适的平台。本章描述了肽纳米纤维作为细胞外基质模拟支架在二维(2D)和三维(3D)多能基质细胞培养系统中的应用,以及使用这些支架进行体外实验的程序。二维和三维肽纳米纤维支架的制备以及细胞培养程序作为体外实验的一部分呈现,包括细胞黏附、活力和铺展分析。通过免疫细胞化学、qRT-PCR和其他针对成骨和成软骨谱系的生化实验,描述了肽纳米纤维支架上细胞分化的分析。
