👥Biography 个人简介
John Dick, PhD is a pioneering cancer biologist at Princess Margaret Cancer Centre who in 1994 provided the first direct experimental evidence for leukemia-initiating cells in human AML using xenotransplantation into SCID mice. His work established the cancer stem cell (CSC) concept for human malignancies and transformed the field of leukemia biology. He holds the Canada Research Chair in Stem Cell Biology.
🧪Research Fields 研究领域
🎓Key Contributions 主要贡献
Discovery of Human Leukemia Stem Cells
In 1994, Dick's lab demonstrated that only the CD34+/CD38- fraction of human AML cells could initiate leukemia in SCID mice, establishing the first functional evidence for a leukemia-initiating cell hierarchy in human cancer.
Xenotransplantation Models for CSC Research
Pioneered and refined xenograft assays using NOD/SCID and NSG mice to prospectively isolate and characterize human leukemia stem cells, creating the gold-standard functional assay for the field.
Clonal Architecture and Evolution in AML
Used single-cell sequencing and xenotransplantation to map clonal hierarchies in AML, revealing how subclonal populations evolve and contribute to relapse, fundamentally informing therapeutic targeting strategies.
Representative Works 代表性著作
Transplantation of normal and leukemic human blood stem cells into immune-deficient mice
Science (1994)
Landmark paper demonstrating that CD34+/CD38- cells from human AML initiate leukemia in SCID mice, founding the cancer stem cell field.
Clonal dynamics of haematopoiesis across the human lifespan
Nature (2020)
Comprehensive single-cell analysis of clonal hematopoiesis architecture and aging, with direct relevance to leukemic transformation.
Human acute myeloid leukemia is organized as a hierarchy that originates from a primitive hematopoietic cell
Nature Medicine (1997)
Extended the CSC model, showing AML hierarchy originates from a primitive stem-like cell distinct from committed progenitors.
