John Dick

Overview

Dr. John Dick and his team investigate the genetic programs that control human blood stem cells (HSCs) to determine how changes in these programs lead to generating leukemia initiating cells. Dr. Dick’s lab has developed a novel NOD/SCID xenotransplant assays for human HSCs and primitive progenitors (Nature 1994) and methods for modelling initiation and progression of leukemia through genetic manipulation (Science 2007) that have provided insight into human hematopoiesis and leukemia development. Dr. Dick has made many advances in these research areas using these systems. Most recently, a major goal within the OICR Cancer Stem Cell Program has been achieved by showing that the genetic characteristics of leukaemia-initiating cells from acute myeloid leukemia (AML) patients are better at predicting clinical outcome than the majority of AML cells. This is the first time it has been described that leukemia initiating cells are significant not just in experimental models but also for patients (Nature Medicine, 2011). His team has also interrogated the genetics of leukemia and discovered that genetic diversity occurs in functionally defined leukaemia-initiating cells and that many diagnostic patient samples contain multiple genetically distinct leukaemia-initiating cell subclones. This will likely be extremely important when considering personalized medicine strategies (Nature 2011). His team has also isolated a human blood stem cell in its purest form – as a single stem cell capable of regenerating the entire blood system (Science 2011). This breakthrough opens the door to harnessing the power of these life-producing cells to treat cancer and other debilitating diseases more effectively.
