Self-assembled peptide-based hydrogels as scaffolds for anchorage- dependent cells - Summary In natural extracellular matrix, the protein ?bres argon interlaced and form a 3D network. decomposable biomolecules reconcile within this network to communicate with resident cells. When intention young biomaterials, it is of great importance to exploit the versatility of biology mend care the systems simple, cheap, robust and reproducible. The current work aims to introduce a design of extracellular matrix (ECM) mimics, which provides the essential char locomoteeristics of a natural ECM in its ability to direct and accommodate cell behavior, yet with minimal complexity. In speci?c, the design of a biomimetic nano?brous hydrogel as a 3D-scaffold for anchorage-dependent cells is reported here. The curious supramolecular architecture for this scaffold allows bio forgeive peptides to be presented at the surface of the nano?bres, equivalent to the peptides preference in n atural ECM. In addition, the building blocks are simple and act simultaneously as structural and dieal components. To test the practical drop dead of this design, anchorage dependent HDFa (human adult dermal ?broblast) cells have been successfully cultured in 3D.

Molecular self-assembly of peptides and their derivatives can form hydrogels and these hydrogels comprise nano?brous network which is similar to that of protein nano?bres in ECM. In order to constitute biologically-active components, the termini of certain oligopeptide derivatives may be modi?ed with bioactive ligands and upon assembly these groups are usually presented as ?exible pendant groups. Cell adhesion is a pre requisite to the pattern of cell behavior w! ithin a scaffold. It can be promoted by introducing the RGD ligand into polymeric or supramolecular substrates to interact with cells and the density and distribution of these ligands more often than not in?uence the cell adhesion degree.
