Abstract
A novel synthetic functionalized backbone polymer is provided which is a polyanionic side-chain functionalized back-bone 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 bio-medical 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.
