γδ T cell-based cancer immunotherapy
Abstract:
γδ T cell-based cancer immunotherapy is attracting attention for the treatment of various malignancies because these cells secrete Th1-type cytokines, exert potent cytotoxicity against a variety of cancer cells. We have established a large-scale in vitro expansion method for Vγ9Vδ2 T cells using zoledronate and interleukin-2. We conducted phase I clinical trials to evaluate safety and anti-tumor effects of intravenous injection of Vγ9Vδ2 T cells in patients with various cancers, and intraperitoneal injection of Vγ9Vδ2 T cells for the treatment of gas- tric cancer with malignant ascites. γδ T cell therapy trials are being conducted with safety and response results already reported for selected cases. Despite the limited number of patients in the phase I studies, the clinical response is thus far promising and warrants further study.

Adult stem cells
Adult stem cells are tissue-specific; hence, they divide to develop the tissue from which they originate. One type of adult stem cell is the epithelial stem cell, which gives rise to the keratinocytes in the multiple layers of epithelial cells in the epidermis of the skin. Adult bone marrow has three distinct types of stem cells:...
