Current approaches to develop bone tissue engineering scaffolds have some limitations and shortcomings. They mainly suffer from combining mechanical stability and bioactivity on the same platform. Synthetic polymers are able to produce mechanically stable sturctures with fibrous morphology when they are electrospun, however, they cannot exhibit bioactivity, which is crucial for tissue engineering and regenerative medicine. One current strategy to bring bioactivity in synthetic materials is to combine extracellular matrix (ECM)-sourced materials with biologically inert synthetic materials. ECM-sourced materials without any modifications are mechanically unstable; therefore, reinforcing them with mechanically stable platforms is indispensable. In order to overcome this bifacial problem, we have demonstrated that poly(butylene adipate-co-terephthalate) (PBAT) electrospun microfibrous membranes can be successfully modified with decellularized bone ECM to endow fibers with bioactive hydrogel and mimic natural micro-features of the native bone tissue. The developed structures have been shown to support osteogenesis, confirmed by histochemical staining and gene expression studies. Furthermore, ECM-coated PBAT fibers, when they were aligned, supplied an improved level of osteogenesis. The strategy demonstrated can be adapted to any other tissues, and the emerging microfibrous, mechanically stable, and bioactive materials can find implications in the specific fields of tissue engineering and regenerative medicine.

3D porous PCL-PEG-PCL / strontium, magnesium and boron multi-doped hydroxyapatite composite scaffolds for bone tissue engineering Yedekçi, Buşra; Tezcaner, Ayşen; Evis, Zafer (2022-01-01) 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 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 HA and PCL-PEG-PCL copolyme...
Improvement of bioactivity with dual bioceramic incorporation to nanofibrous PCL scaffolds Altunordu, Gercem; Tezcaner, Ayşen; Evis, Zafer; Keskin, Dilek (2023-03-01) Bone tissue injuries, diseases or related clinical interventions require bone tissue engineering (BTE) approaches for regeneration of large bone defects, especially for compromised situations. Most BTE applications in literature focused on composites of polymers with a single type of bioceramic. However, native bone matrix has various inorganic components. Accordingly, this study aimed to investigate the use of dual bioceramics in BTE scaffolds prepared by wet-electrospinning of Poly-caprolactone (PCL) and ...

Development and characterization of silk fibroin and citrus pectin based scaffolds for bone tissue engineering Ataol, Sibel; Tezcaner, Ayşen; Akdağ, Akın; Department of Biomedical Engineering (2014) Current strategies of tissue engineering aim to design and develop biologically, physicochemically and mechanically proper scaffolds. Natural polymers are gaining interest in applications since they have already many roles in biochemical pathways and have proper mechanical properties. The objective of this thesis is to develop natural silk fibroin (SF) and citrus pectin (PEC) based three-dimensional porous scaffolds for bone tissue engineering applications. Additionally, we aimed to synthesize nano calcium ...
