  • Hydrogels based on polymers of dextran tyramine and tyramine conjugates of natural polymers
    Patent number: 9132201
    Abstract: The invention relates to composition comprising a dextran-tyramine conjugate and a conjugate selected from the group consisting of chondroitin sulphate-tyramine, collagen-tyramine, chitosan-tyramine, chitosan-phloretic acid, gelatine-tyramine, heparan sulphate-tyramine, keratin sulphate-tyramine, hyaluronic acid-tyramine and heparin-tyramine.
    Type: Grant
    Filed: November 11, 2010
    Date of Patent: September 15, 2015
    Assignee: UNIVERSITY OF TWENTE, INSTITUTE FOR BIOMEDICAL AND TECHNICAL MEDICINE (MIRA)
    Inventors: Hermanus Bernardus Johannes Karperien, Rong Jin, Liliana Sofia Moreira Teixeira, Jan Feijen, Pieter Jelle Dijkstra
  • DEXTRAN-BASED TISSUELETTE CONTAINING PLATELET-RICH PLASMA LYSATE FOR CARTILAGE REPAIR
    Publication number: 20140341874
    Abstract: The invention relates to a dextran-based tissuelette comprising platelet-rich plasma lysate (PRPL), which can be used for tissue repair. In particular, the tissuelette of the present invention can be adapted to display properties similar to natural cartilage, while having increased chondrocyte-attraction. Also, it has a tunable biostability that allows for degradation of the tissuelette material during natural tissue regeneration. In addition, the tissuelette displays full and covalent integration with the surrounding tissue when prepared directly at the site requiring tissue repair. The tissuelette of the present invention is primarily meant for use in cartilage repair, in particular cartilage repair upon degradation by osteoarthritis.
