Beta-Sheet Formation and RGD-Presentation Effects on Osteoblast Differentiation



Carl G. Simon Jr., Matthew Becker, Sheng Lin-Gibson, Kristen E. Roskov, David L. Kaplan, Abby W. Morgan


This report highlights our recent investigation into -sheet formation and RGD epitope presentation on the surface of blended silk films.1 Surface characterization of biomaterials for tissue engineering applications is of great importance to understand how properties drive cellular response. Polymer crystallinity and surface modification with bioactive motifs such as arginine-glycine-aspartate peptide (RGD) alter cell attachment.2,3 In protein-based materials, crystallinity is driven by the transition of -helix to -sheet as is seen in silk.4
