A new scaffold fabrication technique aiming to enhance pore interconnectivity for tissue engineering has been developed. Medical grade poly(lactic acid) was utilized to generate scaffolds by a solvent-evaporating/particulate-leaching technique, using a new dual-porogen system. Water-soluble sodium chloride particles were used to control macro-pore size in(More)
Millions of patients worldwide remain inadequately treated for bone defects related to factors such as disease or trauma. The drawbacks of metallic implant and autograft/allograft use have steered therapeutic approaches towards tissue engineering solutions involving tissue regeneration scaffolds. This study proposes a composite scaffold with properties(More)
The key criteria for assessing the success of bone tissue engineering are the quality and quantity of the produced minerals within the cultured constructs. The accumulation of calcium ions and inorganic phosphates in culture medium serves as nucleating agents for the formation of hydroxyapatite, which is the main inorganic component of bone. Bone nodule(More)
Most of the strategies developed in bone tissue engineering in the past three decades have been aimed to repair/regenerate the tissue with forming elements such as osteoblasts and bone morphogenetic proteins. All these materials are selected as they are known to induce bone formation. Since it is known that bone turnover in basic multicellular units (BMUs)(More)
PURPOSE To evaluate the bone regeneration capacity of bone marrow-derived stem cells (BMSCs) in vertical guided augmentation of bone tissue. MATERIAL AND METHODS The calvaria of 20 rabbits were vertically augmented with autogenous bone graft (ABG); collagen/beta-tricalcium phosphate (β-TCP) linked scaffold transplanted with 15 × 10 BMSCs; or scaffold(More)
In this study, a copolymer of L-lactide and epsilon-caprolactone (Mn: 73,523, Mw: 127,990 and PI: 1.74) was synthesized by ring-opening polymerization by using stannous octoate as the catalyst. FTIR, 1H-NMR and DSC confirmed the copolymer formation. The copolymer films were prepared and a novel method was developed to produce highly porous sponges for(More)
This study aims to establish a facile protocol for the preparation of a bi-layered poly(glycerol-sebacate) (PGS)/β-tricalcium phosphate (β-TCP) construct and to investigate its potential for bone-soft tissue engineering applications. The layered structure was prepared by distributing the ceramic particles within a prepolymer synthesized in a microwave(More)
Decellularization of tissues and organs has high potential to obtain unique conformation and composition as native tissue structure but may result in weakened tissue mechanical strength. In this study, poly(glycerol-sebacate) (PGS) elastomers were combined with decellularized aorta fragments to investigate the changes in mechanical properties. PGS(More)
Corneal tissue engineering efforts to obtain corneal tissue matrices through various types of materials for the replacement of damaged tissues. In this study, three different corneal constructs were prepared and evaluated in terms of morphological, optical, and biological characteristics. Type-I collagen was used to obtain collagen foam scaffolds through(More)
Decellularization of tissues and organs enables researchers to obtain extracellular matrix (ECM) with the natural conformation and chemical composition of specific tissues. However, drawbacks exist such as the structural alteration of ECM or loss of some important components in ECM due to overexposure to chemicals during the decellularization process. In(More)
