Fabrication of 45s5 Bioactive Glass-polycaprolactone Composite Scaffolds
Tissue engineering is a multi-disciplinary field, which aims to apply innovative biomaterials to replace or restore ill or damaged tissues of the human body, such as skin and bones. In particular, porous scaffolds are used as temporary 3D templates to support cell attachment and proliferation during the spontaneous regeneration of natural tissues and this approach is particularly promising for ...
متن کاملEnhanced Stability of Calcium Sulfate Scaffolds with 45S5 Bioglass for Bone Repair
Calcium sulfate (CaSO₄), as a promising tissue repair material, has been applied widely due to its outstanding bioabsorbability and osteoconduction. However, fast disintegration, insufficient mechanical strength and poor bioactivity have limited its further application. In the study, CaSO₄ scaffolds fabricated by using selective laser sintering were improved by adding 45S5 bioglass. The 45S5 bi...
متن کاملThe Use of Carbon Nanotubes to Reinforce 45S5 Bioglass-Based Scaffolds for Tissue Engineering Applications
Bioglass has been used for bone-filling material in bone tissue engineering, but its lean mechanical strength limits its applications in load-bearing positions. Carbon nanotubes (CNTs), with their high aspect ratio and excellent mechanical properties, have the potential to strengthen and toughen bioactive glass material without offsetting its bioactivity. Therefore, in this research, multiwall ...
متن کاملInvestigating the Vascularization of Tissue-Engineered Bone Constructs Using Dental Pulp Cells and 45S5 Bioglass® Scaffolds
Identification of a suitable cell source combined with an appropriate 3D scaffold is an essential prerequisite for successful engineering of skeletal tissues. Both osteogenesis and angiogenesis are key processes for bone regeneration. This study investigated the vascularization potential of a novel combination of human dental pulp stromal cells (HDPSCs) with 45S5 Bioglass® scaffolds for tissue-...
متن کاملBioactive Glass and Glass-Ceramic Scaffolds for Bone Tissue Engineering
Traditionally, bioactive glasses have been used to fill and restore bone defects. More recently, this category of biomaterials has become an emerging research field for bone tissue engineering applications. Here, we review and discuss current knowledge on porous bone tissue engineering scaffolds on the basis of melt-derived bioactive silicate glass compositions and relevant composite structures...
