ABSTRACT:
The invention relates to porous matrices based on a biologically compatible polymer or polymer mixture, to a cell implantation that is established on said matrices and to additional cell implantation based on cell mixtures of hepatocytes and islets of Langerhans. The invention also relates to a method for producing porous matrices, to matrices obtained according to said method and to a special method for obtaining cells for the inoculation of an implantable matrix.
