    Extraction, characterization, and biocompatibility evaluation of type i collagen from chicken feet skin
    (Springer nature, 2025) Zourazema, Sevda; Zendeh, Zahra; Aksun, Elif Tuğçe; Görgün, Büşra; Güzel, Fatma Doğan; Çeçen, Berivan
    The study focused on extracting type I collagen, a protein derived from chicken feet skin, for applications in the biomedical and cosmetic industries. The research thoroughly explored the extraction methodology and characterization techniques and assessed the biocompatibility of the collagen. Acid extraction yielded substantial amounts of type I collagen with an efficiency of 11.35%. The characterization process involved various analyses, including FTIR, SDS-PAGE, western blot, and SEM imaging, to evaluate purity, structural integrity, and morphology. In vitro testing confirmed the biocompatibility of the extracted collagen, indicating its potential as a natural polymer for medical studies. The collagen extracted from chicken feet skin demonstrated significant bioactivity, positioning it as a promising polymer for tissue engineering, wound healing, and cosmetic applications. This study underlines the importance of developing biocompatible biomaterials and provides valuable insights into a sustainable source of collagen from animal by-products.

    Layered double hydroxide-based nanocomposite scaffolds in tissue engineering applications
    (Royal Society of Chemistry, 2021) İzbudak, Burçin; Çeçen, Berivan; Anaya, Ingrid; Kamal Miri, Amir; Bal Öztürk, Ayça; Karaöz, Erdal
    Layered double hydroxides (LDHs), when incorporated into biomaterials, provide a tunable composition, controllable particle size, anion exchange capacity, pH-sensitive solubility, high-drug loading efficiency, efficient gene and drug delivery, controlled release and effective intracellular uptake, natural biodegradability in an acidic medium, and negligible toxicity. In this review, we study potential applications of LDH-based nanocomposite scaffolds for tissue engineering. We address how LDHs provide new solutions for nanostructure stability and enhancein vivostudies' success. © The Royal Society of Chemistry 2021.

    Multi-organs-on-chips for testing small-molecule drugs: challenges and perspectives
    (MDPI, 2021) Çeçen, Berivan; Karavasili, Christina; Nazir, Mubashir; Bhusal, Anant; Doğan, Elvan
    Organ-on-a-chip technology has been used in testing small-molecule drugs for screening potential therapeutics and regulatory protocols. The technology is expected to boost the development of novel therapies and accelerate the discovery of drug combinations in the coming years. This has led to the development of multi-organ-on-a-chip (MOC) for recapitulating various organs involved in the drug–body interactions. In this review, we discuss the current MOCs used in screening small-molecule drugs and then focus on the dynamic process of drug absorption, distribution, metabolism, and excretion. We also address appropriate materials used for MOCs at low cost and scale-up capacity suitable for high-performance analysis of drugs and commercial high-throughput screening platforms. © 2021 by the authors.
