Summary:
Adult stem cells from mice converted to antigen-specific T cells -- the immune cells that fight cancer tumor cells -- show promise in cancer immunotherapy and may lead to a simpler, more efficient way to use the body's immune system to fight cancer, according to Penn State College of Medicine researchers.
By inserting DNA, researchers change the mouse iPS cells into immune cells and inject them into mice with tumors. After 50 days, 100 percent of the mice in the study were still alive, compared to 55 percent of control mice, which received tumor-reactive immune cells isolated from donors. Researchers reported their results and were featured as the cover story in a recent issue of the journal Cancer Research.
