    Engineering Periodontal Tissue Interfaces Using Multiphasic Scaffolds and Membranes for Guided Bone and Tissue Regeneration
    (Elsevier, 2024) Özkendir, Özge; Karaca, İlayda; Çullu, Selin; Yaşar, Hüsniye Nur,; Erdoğan, Oğulcan; Dikici, Serkan; Dikici, Betul Aldemir
    Periodontal diseases are one of the greatest healthcare burdens worldwide. The periodontal tissue compartment is an anatomical tissue interface formed from the periodontal ligament, gingiva, cementum, and bone. This multifaceted composition makes tissue engineering strategies challenging to develop due to the interface of hard and soft tissues requiring multiphase scaffolds to recreate the native tissue architecture. Multilayer constructs can better mimic tissue interfaces due to the individually tuneable layers. They have different characteristics in each layer, with modulation of mechanical properties, material type, porosity, pore size, morphology, degradation properties, and drug-releasing profile all possible. The greatest challenge of multilayer constructs is to mechanically integrate consecutive layers to avoid delamination, especially when using multiple manufacturing processes. Here, we review the development of multilayer scaffolds that aim to recapitulate native periodontal tissue interfaces in terms of physical, chemical, and biological characteristics. Important properties of multiphasic biodegradable scaffolds are highlighted and summarised, with design requirements, biomaterials, and fabrication methods, as well as post-treatment and drug/growth factor incorporation discussed.

    Synergistic Effect of Type and Concentration of Surfactant and Diluting Solvent on the Morphology of Emulsion Templated Matrices Developed as Tissue Engineering Scaffolds
    (Elsevier, 2022) Claeyssens, Frederik; Aldemir Dikici, Betül; Dikici, Serkan
    Emulsion templating is an advantageous route for the fabrication of tissue engineering scaffolds. Emulsions are mostly stabilised using surfactants, and the performances of the surfactants depend on various parameters such as emulsification temperature and the presence of the electrolytes. In this study, we suggest that diluting solvent type also has a dramatic impact on the efficiency of the surfactant and morphology of the polymerised emulsions. For this, morphologies of polycaprolactone methacrylate-based polymerised emulsions, which are designed for tissue engineering applications and in vitro biocompatibilities, were shown by our group, prepared using four different surfactants, and three different solvents were investigated. Results showed that the diluting solvent used in the emulsion composition has a strong impact on the performance of the surfactant and consequently on the morphology of polymerised emulsions. Increasing surfactant concentration and diluting solvent volume have an opposite impact on the characteristics of emulsions. Scaffolds with average pore sizes changing from 10 to 78 μm could be fabricated. Establishing these relations enables us to have control over the overall morphology of polymerised emulsions and precisely engineer them for specific tissue engineering applications by tuning solvent and surfactant type and concentration.

    Glucuronoxylan-Based Quince Seed Hydrogel: a Promising Scaffold for Tissue Engineering Applications
    (Elsevier, 2021) Güzelgülgen, Meltem; Özkendir İnanç, Dilce; Yıldız, Ümit Hakan; Arslan Yıldız, Ahu
    Natural gums and mucilages from plant-derived polysaccharides are potential candidates for a tissue-engineering scaffold by their ability of gelation and biocompatibility. Herein, we utilized Glucuron-oxylanbased quince seed hydrogel (QSH) as a scaffold for tissue engineering applications. Optimization of QSH gelation was conducted by varying QSH and crosslinker glutaraldehyde (GTA) concentrations. Structural characterization of QSH was done by Fourier Transform Infrared Spectroscopy (MR). Furthermore, morphological and mechanical investigation of QSH was performed by Scanning Electron Microscopy (SEM) and Atomic Force Microscopy (AFM). The protein adsorption test revealed the suitability of QSH for cell attachment. Biocompatibility of QSH was confirmed by culturing NIH-3T3 mouse fibroblast cells on it. Cell viability and proliferation results revealed that optimum parameters for cell viability were 2 mg mi(-1)of QSH and 0.03 M GTA. SEM and DAPI staining results indicated the formation of spheroids with a diameter of approximately 300 pm. Furthermore, formation of extracellular matrix (ECM) microenvironment was confirmed with the Collagen Type-I staining. Here, it was demonstrated that the fabricated QSH is a promising scaffold for 3D cell culture and tissue engineering applications provided by its highly porous structure, remarkable swelling capacity and high biocompatibility.
