Dr. Matsui has carried out laboratory-based translational research throughout his career and focused on studying cancer stem cells, tumor cells with enhanced growth potential and their role in clinical oncology. His laboratory first identified cancer stem cells in the plasma cell malignancy multiple myeloma in 2003 and subsequently in other cancers including lymphomas, leukemias and pancreas cancer. His laboratory has also demonstrated that several pathways regulating normal stem cells, including those involved in embryonic development, are abnormally activated in cancer stem cells. Dr. Matsui completed his residency training in internal medicine at the University of Washington in Seattle and his clinical training in medical oncology at Johns Hopkins.
