Cartilage tissue engineering on macroporous scaffolds using human tooth germ stem cells
Koyuncu, A. C. Calikoglu; Pekozer, G. Gurel; Ramazanoğlu, Mehmet Kerim; KÖSE, GAMZE; Hasırcı, Vasıf Nejat (2017-03-01)
The main objective was to study cartilage regeneration through differentiation of human tooth germ stem cells (HTGSCs) into chondrocytes on different three-dimensional (3D) scaffolds (PCL, PLLA and PCL-PLLA). Scaffold topographies were studied by scanning electron microscopy and it was found that the scaffolds had interconnected macroporous structures. HTGSCs were isolated from impacted third molar tooth germs of young adult patients and grown for 3 weeks on the scaffolds in chondrogenic differentiation med...
Tissue engineered cartilage on collagen and PHBV matrices
Kose, GT; Korkusuz, F; Ozkul, A; Soysal, Y; Ozdemir, T; Yildiz, C; Hasırcı, Vasıf Nejat (2005-09-01)
Cartilage engineering is a very novel approach to tissue repair through use of implants. Matrices of collagen containing calcium phosphate (CaP-Gelfix (R)), and matrices of poly(3-hydroxybutyric acid-co-3-hydroxyvaleric acid) (PHBV) were produced to create a cartilage via tissue engineering. The matrices were characterized by scanning electron microscopy (SEM) and electron diffraction spectroscopy (EDS). Porosity and void volume analysis were carried out to characterize the matrices. Chondrocytes were isola...
Tissue engineering of bone on micropatterned biodegradable polyester films
Kenar, H; Kose, GT; Hasırcı, Vasıf Nejat (2006-02-01)
In this study, the effect of cell alignment on proliferation and phenotype expression of rat bone marrow derived osteoblasts on micropatterned (MP) PHBV and P(L/D,L)LA films with 27 mu m wide parallel microgrooves was investigated. Immobilization of fibrinogen (Fb) on film surface by adsorption increased hydrophilicity, while covalent immobilization decreased it. Amount of Fb immobilized was significantly higher upon covalent bonding (153.1 +/- 42.4 mu g Fb/cm(2)) than when adsorbed (10.0 +/- 3.3 mu g Fb/cm...
Mechanical design, analysis, and laboratory testing of a dental implant with axial flexibility similar to natural tooth with periodontal ligament
Pektas, Omer; Tönük, Ergin (2014-11-01)
At the interface between the jawbone and the roots of natural teeth, a thin, elastic, shock-absorbing tissue, called the periodontal ligament, forms a cushion which provides certain flexibility under mechanical loading. The dental restorations supported by implants, however, involve comparatively rigid connections to the jawbone. This causes overloading of the implant while bearing functional loading together with neighboring natural teeth, which leads to high stresses within the implant system and in the j...
Hyperspectral image processing of eo-1 hyperion data for lithological and mineralogical mapping
San, Bekir Taner; Süzen, Mehmet Lütfi; Department of Geological Engineering (2008)
Hyperspectral data is a powerful tool for mineral explorations and lithological discriminations. EO1-Hyperion is a space borne hyperspectral system for hyperspectral imaging which is capable of 220 spectral image channels within the range of 400 to 2500 nm wavelengths. It has advantages over airborne systems such as data cost and coverage area. Although it has many advantages, much more uncertainty exists in application period, of which this uncertainty does exist in all processing stages starting from the ...
