Abstract Three-dimensional (3D) extrusion-based bioprinting is widely used in tissue
engineering and regenerative medicine to create cell-incorporated constructs or scaffolds …

The tissue engineering approach for repairing osteochondral (OC) defects involves the
fabrication of a biological tissue scaffold that mimics the physiological properties of natural …

The pore architecture of porous scaffolds is a critical factor in osteogenesis, but it is a
challenge to precisely configure strut-based scaffolds because of the inevitable filament …

Extrusion bioprinting has been widely used to extrude continuous filaments of bioink (or the
mixture of biomaterial and living cells), layer-by-layer, to build three-dimensional constructs …

Bone transplant is still the gold standard approach when dealing with orthopedic trauma or
disease. When this solution is not possible, scaffolding is a possibility provided by bone …

Auxetic structures are a special class of structural components that exhibit a negative
Poisson's ratio (NPR) because of their constituent materials, internal microstructure, or …

Bone scaffolds should have good biocompatibility and mechanical and biological properties,
which are primarily by the material design, porous structure, and preparation process. In this …

Abstract Background: Three-dimensional (3D) printed bone tissue engineering scaffolds
have been widely used in research and clinical applications. β-TCP is a biomaterial …

Scaffolds obtained from polycaprolactone (PCL) have received extensive explorations due
to their biocompatibility and biomechanical features. Nevertheless, weak hydrophilicity limits …

As a new generation of materials/structures, heterostructure is characterized by
heterogeneous zones with dramatically different mechanical, physical or chemical …
