1. An in vitro system which maintains different cell types in a viable state comprising:

  • a plurality of cell culture chambers each containing the different cell types in a culture medium containing a substance to be evaluated;

    a gas-liquid exchange device;

    a conduit system to conduct culture medium between said gas-liquid exchange device and said plurality of cell culture chambers;

    a circulation mechanism for circulating culture medium through said conduit system, said plurality of cell culture chambers, and said gas-liquid exchange device, including circulating culture medium between said plurality of cell culture chambers, wherein the substance to be evaluated contacts the different cell types, thereby producing either metabolites of the substance to be evaluated or metabolites of the different cell types; and

    a microprocessor to control operation of said gas-liquid exchange device and said circulation mechanism, wherein said plurality of cell culture chambers, said conduit system, and said circulation mechanism are configured such that the metabolites of the different cell types or the metabolites of the substance to be evaluated are exchanged between said plurality of cell culture chambers.
