Composite Scaffolds for Bone Tissue Engineering
Biomaterial and scaffold development underpins the advancement of tissue engineering. Traditional scaffolds based on biodegradable polymers such as poly(lactic acid) and poly(lactic acidco-glycolic acid) are weak and non-osteoconductive. For bone tissue engineering, polymer-based composite scaffolds containing bioceramics such as hydroxyapatite can be produced and used. The bioceramics can be e...
متن کاملFabrication of Porous Hydroxyapatite-Gelatin Composite Scaffolds for Bone Tissue Engineering
Background: engineering new bone tissue with cells and a synthetic extracellular matrix represents a new approach for the regeneration of mineralized tissues compared with the transplantation of bone (autografts or allografts). Methods: in this study, to mimic the mineral and organic component of natural bone, hydroxapatite (HA) and gelatin (GEL) composite scaffolds were prepared. The raw mater...
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 کاملBiodegradable Polymer-bioceramic Composite Scaffolds for Bone Tissue Engineering
Critical size bone defects due to trauma or disease are very difficult to repair via the natural growth of the host bone. Therefore, these defects must be filled with a bridging material (scaffold), which should also, in combination with relevant cells and signalling molecules, promote the regeneration of new bone tissue. In this context, bone regeneration is one of the most attractive areas in...
متن کاملBiomimetic Calcium Phosphate-Polycarbonate Composite Scaffolds for Bone Tissue Engineering
Shuang S Chen and Joachim Kohn New Jersey Center for Biomaterials, Rutgers The State University of New Jersey, Piscataway, New Jersey 08854, United States. Statement of Purpose: Large bone defects resulting from trauma, tumor resection, congenital abnormalities or reconstructive surgery are challenging clinical problems that are usually treated with autografts and allografts. However, donor sit...
