Most cells assemble rich FN matrices via an integrin-dependent process that incorporates FN molecules into matrix fibrils. We have shown this process can occur by simple adsorption of individual FN molecules onto particular surface chemistries – in absence of cells. FN – material interactions would induce exposure of self-assembly sites to drive FN assembly, a process that we named material-driven FN fibrillogenesis.
The resulting FN matrix assembled at the material interface consists of a protein network with enhanced biological activity: it supports cell adhesion, matrix remodeling, and trigger cell differentiation. Moreover, it provides a robust platform to engineer advanced microenvironments in combination with growth factors to tune stem cell differentiation and promote tissue repair.
