Fabrication of 3D Scaffolds with Precisely Controlled Substrate Modulus and Pore Size by Templated-Fused Deposition Modeling to Direct Osteogenic Differentiation.

Scaffolds with tunable mechanical and topological properties fabricated by templated-fused deposition modeling promote increased osteogenic differentiation of bone marrow stem cells with increasing substrate modulus and decreasing pore size. These findings guide the rational design of cell-responsive scaffolds that recapitulate the bone microenvironment for repair of bone damaged by trauma or disease.
