Nano- and micro-fiber combined scaffolds: a new architecture for bone tissue engineering.
One possible interesting way of designing a scaffold for bone tissue engineering is to base it on trying to mimic the biophysical structure of natural extracellular matrix (ECM). This work was developed in order to produce scaffolds for supporting bone cells. Nano and micro fiber combined scaffolds were originally produced from starch based biomaterials by means of a fiber bonding and a electro...
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 کاملEndothelial cell colonization and angiogenic potential of combined nano- and micro-fibrous scaffolds for bone tissue engineering.
Presently the majority of tissue engineering approaches aimed at regenerating bone relies only on post-implantation vascularization. Strategies that include seeding endothelial cells (ECs) on biomaterials and promoting their adhesion, migration and functionality might be a solution for the formation of vascularized bone. Nano/micro-fiber-combined scaffolds have an innovative structure, inspired...
متن کاملMicro/Nano Multilayered Scaffolds of PLGA and Collagen by Alternately Electrospinning for Bone Tissue Engineering
The dual extrusion electrospinning technique was used to fabricate multilayered 3D scaffolds by stacking microfibrous meshes of poly(lactic acid-co-glycolic acid) (PLGA) in alternate fashion to micro/nano mixed fibrous meshes of PLGA and collagen. To fabricate the multilayered scaffold, 35 wt% solution of PLGA in THF-DMF binary solvent (3:1) and 5 wt% solution of collagen in hexafluoroisopropan...
متن کاملA 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...
