1. A method for implanting cells into a host tissue comprising the steps of:

  • providing an implant assembly for holding cells including wall means having an interior surface defining a chamber for holding cells for implantation and exterior surface defining an interface with the host tissue, the wall means having a pore size sufficient to isolate the implanted cells from the immune response of the host tissue and having a metabolic transit value sufficient to sustain viability of implanted cells during ischemia, the exterior surface having a conformation which allows growth of vascular structures by the host tissue close to but not substantially into the interface, the implant assembly including a port;

    adding cells into the chamber of the implant assembly through the port; and

    implanting the implant assembly and port within a host.
