Control of stem cell response and bone growth on biomaterials by fully non-peptidic integrin selective ligands

Abstract

In this communication we report that anchoring αvβ3 or α5β1 integrin-selective RGD peptidomimetics to titanium efficiently tunes mesenchymal stem cell response in vitro and bone growth in rat calvarial defects. Our results demonstrate that this molecular chemistry-derived approach could be successful to engineer instructive coatings for orthopedic applications.
