Native extracellular matrix coating on Ti surfaces

Abstract

Osteoblast-like SAOS-2 cells were allowed to synthesize and assemble their extracellular matrix (ECM) on titanium surfaces. After the selective removal of cells, Ti coated with a native ECM was obtained (ECM-Ti). The responses of SAOS-2 cells to ECM-Ti compared with those to peptide sequence RGDS- or fibronectin-immobilized Ti were examined, demonstrating the compositional and structural effects needed to trigger the native cell behavior.
