A 3D nanostructured calcium-aluminum-silicate scaffold with hierarchical meso-macroporosity for bone tissue regeneration: Fabrication, sintering behavior, surface modification and in vitro studies

Bioinspired fabrication of 3D hierarchical porous nanomicrostructures of calcium carbonate for bone regeneration.

Hierarchical calcium carbonate structures with multi-scale organization have been successfully fabricated covering the full range of pore sizes from nano-, to micro- to macrofeatures. The resulting 3D scaffolds, with a close resemblance to bone structures, have been evaluated in vitro and in vivo and showed great potential for bone regeneration.

Laser Sintered Magnesium-Calcium Silicate/Poly-ε-Caprolactone Scaffold for Bone Tissue Engineering

In this study, we manufacture and analyze bioactive magnesium-calcium silicate/poly-ε-caprolactone (Mg-CS/PCL) 3D scaffolds for bone tissue engineering. Mg-CS powder was incorporated into PCL, and we fabricated the 3D scaffolds using laser sintering technology. These scaffolds had high porosity and interconnected-design macropores and structures. As compared to pure PCL scaffolds without an Mg-...

A Review on Commonly Used Scaffolds in Tissue Engineering for Bone Tissue Regeneration

Introduction: Bone is one of the tissues that have a true potential for regeneration. However, sometimes the bone defects are so outsized that there is no chance of bone self-repair and restoration or the damage is such that it is not possible to repair with medical or surgical interventions. In these situations, bone grafts are the treatment of choice, but due to several obstacles, including l...
