  1. 1. Production of neocartilage tissues using primary chondrocytes

    Author : Janne Ylärinne; Mikko Lammi; Chengjuan Qu; Mats Brittberg; Umeå universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

    Author : Yu Zhang; Dmitri Ossipov; Carsten Werner; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; hyaluronan; hydrogel; scaffold; tissue engineering; imaging; interpenetrating network; MRI; fluorescence imaging; scaffold degradation;

    Abstract : 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. READ MORE

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

    Author : Lavinia Cicortas Gunnarsson; Institutionen för immunteknologi; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 4. Synthesis of Biomedical Polymers and Scaffold Design

    Author : Therese Tyson; Ann-Christine Albertsson; KTH; []
    Keywords : 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;

    Abstract : 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.

  5. 5. Engineering and Functionalization of Degradable Scaffolds for Medical Implant Applications

    Author : Yang Sun; Anna Finne-Wistrand; Ann-Christine Albertsson; Minna Kellomäki; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tissue engineering; nanodiamond; scaffold; bioreactor; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : The treatment of bone defects is facing the situation of lacking donations for autotransplantation. As a valid approach, scaffold-based tissue engineering combines the construction of well-defined porous scaffolds with advanced cell culturing technology to guide tissue regeneration. READ MORE
