1. A method of manufacturing an implantable, biocompatible cell encapsulation device comprising:

  • (a) forming a jacket comprising a permeable biocompatible material;

    (b) loading the jacket with a core comprising a reticulate foam scaffold having interconnected pores, the pore density of the foam varying between 20%-90%, the core further comprising a population of living mammalian cells dispersed in the pores;

    (c) sealing the jacket;

    wherein the jacket provides at least one permeable membrane surface which permits passage of biologically active substances across said membrane while preventing passage of mammalian cells thereacross.
