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...
متن کاملBioactive Glass Scaffolds for Bone Tissue Engineering
In materials science, the ability to develop porous constructs with high mechanical strength is important for a broad range of emerging applications, including filters, catalyst support, and tissue engineering scaffolds. Particularly for orthopedic surgery, the regeneration of large bone defects in load-bearing limbs remains a challenging problem that require scaffolds that combine the strength...
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...
متن کاملAligned and random nanofibrous nanocomposite scaffolds for bone tissue engineering
Aligned and random nanocomposite nanofibrous scaffolds were electrospun from polycaprolactone (PCL), poly (vinyl alcohol) (PVA) and hydroxyapatite nanoparticles (nHA). The morphology and mechanical characteristics of the nanofibers were evaluated using scanning electron microscopy and tensile testing, respectively. Scanning electron microscopy revealed fibers with an average diameter of 123 ± 3...
متن کاملBone Tissue Engineering: Scaffolds with Osteoinductivity for Bone Regeneration
Biological mechanism of bone repair mainly involves both osteoconductivity and osteoinductivity. Scaffolds with osteoinductivity can give biological signals to stimulate the proliferation and differentiation of bone marrow mesenchymal stem cells and osteoblast-like cells to promote bone regeneration. Although most scaffolds for bone tissue engineering demonstrate osteoconductivity, they lack os...
