Volumetric muscle loss (VML) due to trauma and tumor removal operations affects millions of people every year. Although skeletal muscle has a natural repair mechanism, it cannot provide self-healing above a critical level of VML. In this study, nanocomposite aligned fiber scaffolds as support materials were developed for volumetric skeletal muscle regeneration. For this purpose, silver nanowire (Ag NW) loaded poly(ε-caprolactone) (PCL) nanocomposite fiber scaffolds (PCL-Ag NW) were prepared to mimic the aligned electroactive structure of skeletal muscle and provide topographic and conductive environment to modulate cellular behavior and orientation. A computer-aided rotational wet spinning (RWS) system was designed to produce high-yield fiber scaffolds. Nanocomposite fiber bundles with lengths of 50 cm were fabricated via this computer-aided RWS system. The morphological, chemical, thermal properties and biodegradation profiles of PCL and PCL-Ag NW nanocomposite fibers were characterized in detail. The proliferation behavior and morphology of C2C12 mouse myoblasts were investigated on PCL and PCL-Ag NW nanocomposite fibrous scaffolds with and without electrical stimulation. Significantly enhanced cell proliferation was observed on PCL-Ag NW nanocomposite fibers compared to neat PCL fibers with electrical stimulations of 1.5 V, 3 V and without electrical stimulation.

Dual growth factor delivery using PLGA nanoparticles in silk fibroin/PEGDMA hydrogels for articular cartilage tissue engineering Fathi-Achachelouei, Milad; Keskin, Dilek; Bat, Erhan; Vrana, Nihal E.; Tezcaner, Ayşen (Wiley, 2020-07-01) Degeneration of articular cartilage due to damages, diseases, or age-related factors can significantly decrease the mobility of the patients. Various tissue engineering approaches which take advantage of stem cells and growth factors in a three-dimensional constructs have been used for reconstructing articular tissue. Proliferative impact of basic fibroblast growth factor (bFGF) and chondrogenic differentiation effect of transforming growth factor-beta 1 (TGF-beta 1) over mesenchymal stem cells have previou...
Alternative Polyadenylation patterns for novel gene discovery and classification in cancer Beğik, Oğuzhan; Öyken, Merve; Can, Tolga; Erson Bensan, Ayşe Elif (2017-06-03) Certain aspects of diagnosis, prognosis and treatment of cancer patients are still important challenges to be addressed. Therefore, we propose a pipeline to uncover patterns of alternative polyadenylation (APA), a hidden complexity in cancer transcriptomes, to further accelerate efforts to discover novel cancer genes and pathways. Here, we analyzed expression data for 1,045 cancer patients and found a significant shift in usage of poly(A) signals in cancers. Using machine-learning techniques, we further def...

Here, we analyzed expression data for 1045 cancer patients and found a significant shift in usage of poly(A) signals in common tumor types (breast, colon, lung, prostate, gastric...
Bacterial cellulose-reinforced boron-doped hydroxyapatite/gelatin scaffolds for bone tissue engineering Atila, Deniz; Karataş, Ayten; Evcin, Atilla; Keskin, Dilek; Tezcaner, Ayşen (Springer Science and Business Media LLC, 2019-12-01) Today, many people are suffering from bone defects due to trauma, tumor or bone related diseases. Mimicking bone in terms of composition and structure has been a challenge for tissue engineers. In this study, a novel 3D porous tissue-engineered construct composed of natural and easily-accessible biomaterials, namely (1) an exopolysaccharide; bacterial cellulose (BC), (2) mineral crystals; boron-doped nano-hydroxyapatite (BHA), and (3) a natural protein; gelatin (GEL) as the main constituting biomaterial was...
3D Porous Composite Scaffold of PCL-PEG-PCL/Sr2+ and Mg2+ Ions Co-Doped Borate Hydroxyapatite for Bone Tissue Engineering Yedekçi, Buşra; Evis, Zafer; Tezcaner, Ayşen; Department of Engineering Sciences (2021-9-6) Bioceramic/polymer composite systems have gained importance in treating hard tissue damages using bone tissue engineering (BTE). In this context, it was aimed to develop 3D porous composite PCL-PEG-PCL scaffolds containing different amounts of B, Sr and Mg multi-doped hydroxyapatite (HA) that can provide bone regeneration in the bone defect area and to investigate the effect of both the amount of inorganic phase and the porosity on the mechanical and the biological properties. B-Sr-Mg multi-doped HAs were s...
