Abstract

A test system and method are disclosed for using tissue analogs The method includes the following steps: (1) isolating the cells to be implanted from donor tissue; (2) seeding the cells onto a particulate microcarrier bead; (3) culturing the cells on the microcarriers to achieve an expansion in the number of cells; and (4) further culturing the cell-particle aggregates to form a tissue analog. The resulting tissue analog and test system may be used for use in screening drugs for diseases and pathological conditions, for testing for toxicity of chemical agents, or for genomic or proteomic screening. The tissue analogs may also be subjected to conditions that will induce disease-like conditions such that the resulting diseased tissue analogs may be used to screen for therapeutic drugs that modify the diseased tissue analog physiology or block progression of the diseased conditions. Kits may be developed for the purpose of conducting multiple tests in conventional multi-well plate systems.
