    • A one-step method for producing antigen loaded antigen-presenting cells from monocytes ex vivo has been found which comprises contacting the monocytes with a composition comprising an activator such as TNF alpha preferably in combination with at least one growth factor such as GM-CSF and at least one soluble or particulate antigen. According to the methods of the present invention, antigen-loaded dendritic cell vaccines can be generated within as little as three (3) days. In another method of the present invention, antigen loaded antigen-presenting cells are produced from monocytes ex vivo by contacting the monocytes with TNF alpha and granulocyte-macrophage colony stimulating factor at one time point to form antigen-presenting cells and then contacting antigen­presenting cells with soluble or particulate antigenic material at a second time point to form antigen loaded antigen-presenting cells, wherein the antigen loaded antigen-presenting cells are produced in less than four days. The present invention also includes a vaccine which comprises monocyte-derived antigen loaded antigen-presenting cells, wherein the antigen­presenting cells are composed of two or more subsets selected from the group consisting of Langerhans cells with surface markers (CD 1 a+ CD207+); interstitial dendritic cells with surface markers (CD 1a+ CD207-); double negative dendritic cells with surface markers 20 (CD 1 a-CD 14-); and dendritic cells with surface markers (CD 14+ CD 1 a- CD209+).

    • 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.

    • A method for producing human dendritic cells for therapeutic purposes which allows culture-deriving dendritic cells using no cytokines, or reduced cytokines. The method involves culturing mononuclear cells from blood or bone marrow in a medium containing at least one agent such as a calcium ionophore, e.g. A23187, theophylline, protaglandin E1, dibutyryl cyclic AMP, Vitamin D3, Vitamin E, retinoic acid, or a fatty acid. The culture is maintained for a sufficient time, typically 4 - 14 days, to produce a culture enriched for dendritic cells, as evidenced by at least about 2.5 % of total cells exhibiting dendritic cell processes, or a dendritic cell antigen such as CD80, CD86, or CD1a. Also provided is a method to produce antigen-specific human T-cells by pulsing the dendritic cells obtained by the method of the invention with an antigen such as a viral, tumor, bacterial, or cell surface antigen, and then co-culturing T-cells with the antigen-pulsed dendritic cells. Useful for treatment of viral or bacterial infections, useful as a cancer vaccine, useful to induce tolerance of allo- or xeno-graft.
