1. A method for detecting T cell mediated anti-cancer cell activity of a target antigenic peptide, comprising:
transforming a hematopoietic stem cell in vitro with a recombinant expression cassette comprising a nucleic acid encoding the target antigenic peptide, and differentiating the transformed stem cell into a transformed dendritic cell;
contacting a T cell with the transformed dendritic cell, thereby providing an activated T cell, wherein the T cell and the hematopoietic stem cell are from the same individual;
contacting a cancer cell expressing a protein comprising the target antigenic peptide with the activated T cell; and,
monitoring the effect of the activated T cell on the cancer cell, thereby detecting the anti cancer cell activity of the target antigenic peptide.
