Abstract

We report here a designer self‐assembling peptide nanofiber scaffold developed specifically for nerve tissue engineering. We synthesized a peptide FGL‐RADA containing FGL (EVYVVAENQQGKSKA), the motif of neural cell adhesion molecule (NCAM), and then attended to make a FGL nanofiber scaffold (FGL‐NS) by assembling FGL‐RADA with the peptide RADA‐16 (AcN‐RADARADARADARADA‐CONH2). The microstructures of the scaffolds were tested using atomic force microscopy (AFM), and rheological properties of materials were accessed. Then we demonstrated the biocompatibility and bioactivity of FGL‐NS for rat dorsal root ganglion neurons (DRGn). We found that the designer self‐assembling peptide scaffold was noncytotoxic to neurons and able to promote adhesion and neurite sprouting of neurons. Our results indicate that the designer peptide scaffold containing FGL had excellent biocompatibility and bioactivity with adult sensory neurons and could be used for neuronal regeneration. © 2010 Wiley Periodicals, Inc.
