  1. 1. Production of neocartilage tissues using primary chondrocytes

    Författare :Janne Ylärinne; Mikko Lammi; Chengjuan Qu; Mats Brittberg; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; primary chondrocytes; articular cartilage; tissue engineering; neocartilage; scaffold; scaffold-free; hyaluronan; self-assembling peptide; TGF-β3; glucosamine sulfate; hypoxia; hypertonic medium; glucose;

    Sammanfattning : Hyaline cartilage is a highly specialized tissue, which plays an important role in the articulating joints of an individual. It provides the joints with a nearly frictionless, impact resisting surface to protect the ends of the articulating bones. LÄS MER

  2. 2. Hyaluronan Based Biomaterials with Imaging Capacity for Tissue Engineering

    Sammanfattning : This thesis presents the preparation of hyaluronan-based biomaterials with imaging capability and their application as scaffolds in tissue engineering. First, we have synthesized HA derivatives functionalized with different chemoselective groups. LÄS MER

  3. 3. Novel binding specificities engineered into the scaffold of a carbohydrate binding module

    Författare :Lavinia Cicortas Gunnarsson; Institutionen för Immunteknologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bioteknik; Biotechnology; carbohydrate binding module; binding specificity; selection; combinatorial library; scaffold; protein engineering;

    Sammanfattning : The growing field of biotechnology is in constant need of proteins that can function as recognition tools for separational, analytical and therapeutic purposes. Different molecular engineering approaches are applied on natural proteins in order to create variants with desired properties. LÄS MER

  4. 4. Functional Fibers for Biomedical and Thermal Management Applications

    Författare :Carl Zandén; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; MEDICIN OCH HÄLSOVETENSKAP; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; MEDICAL AND HEALTH SCIENCES; microsystems; thermal management; thermal interface material; cell-scaffold interaction; metal matrix composite; fibers; microfluidic system; plasma surface modification; scaffold; electrospinning;

    Sammanfattning : This thesis explores the integration of electrospun polymeric structures in two fields; fibrous scaffolds as cell culture substrates for biomedical applications and fiber carrier networks in metal matrix polymer composites as thermal interface materials in microsystems. Electrospinning has been found to carry great potential for a range of future biomedical engineering applications. LÄS MER

  5. 5. Synthesis of Biomedical Polymers and Scaffold Design

    Författare :Therese Tyson; Ann-Christine Albertsson; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; ring-opening polymerization; tin alkoxide initiator; stannous octoate; poly p-dioxanone ; copolymer; L-lactide; trimethylene carbonate; degradable porous scaffold; Polymer chemistry; Polymerkemi;

    Sammanfattning : This work has focused on the development of new improved synthesis methods of biodegradable aliphatic polymers and on the preparation of porous scaffolds for tissue engineering applications. The aim of the first part of the work was the synthesis of poly(p-dioxanone) (PPDX) homopolymers with high molecular weights using the cyclic tin alkoxide initiator 1-di-n-butyl-1-stanna-2,5-dioxacyclopentane.
