Fabrication of Polymer Scaffolds for Tissue Engineering
A new approach to the fabrication of individual implants and scaffolds for tissue engineering—surface selective laser sintering (SSLS)—is proposed and realized. In contrast to the conventional selective laser sintering, the SSLS method makes it possible to sinter polymer microparticles and melt the near-surface layer rather than the microparticle as a whole. The effect of the laser radiation pa...
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 کاملFabrication of Porous Hydroxyapatite-Gelatin Scaffolds Crosslinked by Glutaraldehyde for Bone Tissue Engineering
In this study, to mimic the mineral and organic components of natural bone, hydroxyapatite[HA] and gelatin[GEL] composite scaffolds were prepared using the solvent-casting method combined with a freeze drying process. Glutaraldehyde[GA] was used as a cross linking agent and sodium bisulfite was used as an excess GA discharger. Using this technique, it is possible to produce scaffolds with mecha...
متن کاملFabrication of three-dimensional scaffolds for heterogeneous tissue engineering.
The development of biomedical scaffolds mimicking a heterogeneous cellular microenvironment for a specified regulation of cell-fates is very promising for tissue engineering. In this study, three-dimensional scaffolds with heterogeneous microstructure were developed using a DMD-PP apparatus. During the fabrication process, this apparatus can efficiently switch monomers to form microstructures w...
متن کاملFabrication of Poly(ε-Caprolactone), Hydrophilic and β-Tricalcium Phosphate Layer- by -Layer Nanofibrous Scaffolds for Tissue Engineering
In this study, using biodegradable polymers, nanofiberouse scaffolds were fabricated from the layer-by-layer electrospinning method, including two layer that poly (ε-caprolactone), polyvinylpyrrolidone deposited at first layer and poly (ε-caprolactone), polyvinyl alcohol , β-tricalcium phosphate at latter. After prepration of scaffolds, scanning electron microscopy (SEM), swelling, porosity, me...
