Composite clinoptilolite/PCL-PEG-PCL scaffolds for bone regeneration: In vitro and in vivo evaluation
Pazarçeviren, Ahmet Engin; Altunbas, Korhan; Yaprakci, Volkan; Erdemli, Ozge; Keskin, Dilek; Tezcaner, Ayşen (Wiley, 2020-01-01)
In this study, clinoptilolite (CLN) was employed as a reinforcement in a polymer-based composite scaffold in bone tissue engineering and evaluated in vivo for the first time. Highly porous, mechanically stable, and osteogenic CLN/PCL-PEG-PCL (CLN/PCEC) scaffolds were fabricated with modified particulate leaching/compression molding technique with varying CLN contents. We hypothesized that CLN reinforcement in a composite scaffold will improve bone regeneration and promote repair. Therefore, the scaffolds we...
Poly( amino acid)-based fibrous scaffolds modified with surface-pendant peptides for cartilage tissue engineering
Svobodova, Jana; Proks, Vladimir; Karabiyik, Ozge; Koyuncu, Ayse Ceren Calikoglu; Kose, Gamze Torun; Rypacek, Frantisek; Studenovska, Hana (Wiley, 2017-03-01)
In this study, fibrous scaffolds based on poly(gamma-benzyl-L-glutamate) (PBLG) were investigated in terms of the chondrogenic differentiation potential of human tooth germ stem cells (HTGSCs). Through the solution-assisted bonding of the fibres, fully connected scaffolds with pore sizes in the range 20-400 mu m were prepared. Biomimetic modification of the PBLG scaffolds was achieved by a two-step reaction procedure: first, aminolysis of the PBLG fibres' surface layers was performed, which resulted in an i...
Preparation of Hydroxyapatite-Titania Hybrid Coatings on Titanium Alloy
Un, Serhat; Durucan, Caner (Wiley, 2009-08-01)
Hydroxypapatite-titania hybrid films on Ti6Al4V alloys were prepared by sol-gel technique by incorporating presynthesized hydroxypapatite (Ca-10(PO4)(6)(OH)(2) or HAp) powders into a titanium-alkoxide dip coating solution. Titania network was formed by the hydrolysis and condensation of Ti-isopropoxide Ti[OCH(CH3)(2)](4)-based sols. The effect of titania sol formulation, specifically the effect of organic solvents on the microstructure of the dip coated films calcined at 500 degrees C has been investigated....
Fabrication and cellular interactions of nanoporous tantalum oxide
Uslu, Ece; Garipcan, Bora; Ercan, Batur (Wiley, 2020-10-01)
Tantalum possesses remarkable chemical and mechanical properties, and thus it is considered to be one of the next generation implant materials. However, the biological properties of tantalum remain to be improved for its use in tissue engineering applications. To enhance its cellular interactions, implants made of tantalum could be modified to obtain nanofeatured surfaces via the electrochemical anodization process. In this study, anodization parameters were adjusted to obtain a nanoporous surface morpholog...
Fabrication of functionalized citrus pectin/silk fibroin scaffolds for skin tissue engineering
Türkkan, Sibel; Atila, Deniz; Akdağ, Akın; Tezcaner, Ayşen (Wiley, 2018-10-01)
In this study, novel porous three-dimensional (3D) scaffolds from silk fibroin (SF) and functionalized (amidated and oxidized) citrus pectin (PEC) were developed for skin tissue engineering applications. Crosslinking was achieved by Schiff's reaction in borax presence as crosslinking coordinating agent and CaCl2 addition. After freeze-drying and methanol treatment, plasma treatment (10 W, 3 min) was applied to remove surface skin layer formed on scaffolds. 3D matrices had high porosity (83%) and interconnec...
