Large and Small Assembly: Combining Functional Macromolecules with Small Peptides to Control the Morphology of Skeletal Muscle Progenitor Cells

Abstract

The material properties of natural tissues, such as skeletal muscle, are highly sophisticated and are synthetically challenging to mimic. Using natural biomacromolecules to functionalize self-assembled peptide (SAP) hydrogels has the potential to increase the utility of these materials by more closely reproducing the natural cellular environment. Here, to demonstrate that a conserved co-assembly pathway can retain distinct function, the biocompatible peptide derivative Fmoc-FRGDF was co-assembled with either a sulfated polysaccharide, fucoidan, or the provisional matrix proteoglycan, versican. Our results demonstrate that thermodynamically driven co-assembly with biologically active macromol..
