  • Novel Synthetic Polymers and Crosslinked Hydrogel Systems
    Publication number: 20240150509
    Abstract: A novel synthetic functionalized backbone polymer is provided which is a polyanionic side-chain functionalized backbone polymer comprising a hydrophilic backbone polymer functionalized with an activated alkene or epoxy group. The functionalized backbone polymer may be combined with a free or protected thiol-containing compound to form a crosslinked hydrogel having biomedical application, and may additionally be combined with a hydrogel matrix to yield a hydrogel system useful for in vivo delivery of cells and other therapeutic agents.
    Type: Application
    Filed: January 9, 2024
    Publication date: May 9, 2024
    Inventors: Sarah Alison Stewart, Harald Donald Helmut Stover, Michael Bradley Coulson
