  • Encapsulation of cells in biologic compatible scaffolds by coacervation of charged polymers
    Publication number: 20060019362
    Abstract: This invention relates to a method for the encapsulation of cells in biologic compatible three dimensional scaffolds and the use of such cells encapsulated in a scaffold. The cells are embedded in a charged polymer that is complex coacervating with an oppositely charged polymer within biologic compatible scaffolds. The polymer complex embedding the cells is forming an ultra thin membrane on the surface of the three dimensional scaffold.
