ABSTRACT
Fibrous networks assembled from synthetic peptides are promising candidates for biomimetic cell culture platforms and implantable biomaterials. The ability of the materials to reproduce physiological cell-matrix interactions is essential. However, the synthetic complexity of such systems limits their applications, thus alternative materials are desirable. Here, we design lysozyme derived amyloid fibril networks with controllable topographies, and perform a comprehensive study of the response of cultured fibroblast and epithelial cells. At high surface coverage a favorable increase in spreading and the generation of focal adhesions was observed, due to a combination of biomimetic chemistry and morphology. Their ease of synthesis, makes the nanoscale fibrils presented here ideal materials for future clinical applications whereby large volumes of biomimetic biomaterials are required. Furthermore, the surface chemistry of the fibrils is sufficient for the promotion of focal adhesions with cultured cells, eliminating the need for complex protocols for fibril decoration with bioactive moieties.
