The potential of self-assembling peptides RAD-16-II and collagen-alginate composites to maintain vocal fibroblasts and stimulate the synthesis and accumulation of ECM in 3D cell culture with minimal matrix contraction was demonstrated. The peptide RAD-16-II represents one of a class of self-assembling peptides developed through molecular engineering. These peptides were found to assemble into well-ordered nano-fibers with inter-fiber spacing of ∼50-20 nm, creating a nanoscale hydrogel network around encapsulated cells. Alginate was studied extensively as a tissue engineering matrix for cartilage and for soft tissue augmentation.
