( using the disease only arose from imm...)Cancer scientists create 'human' leukemia process to map how disease begins, progresses

using, the disease only arose from immature stem and progenitor cells. The leukemic stem cells that were created seemed to change as the human leukemia was grown for longer times in a series of transplanted mice. Our findings of how these leukemic stem cells functioned could explain several features of the leukemia in children and adults that also contain the same leukemia gene, MLL-ENL."

In 1994, Dr. Dick identified the first cancer stem cell in leukemia, following on the original discovery in 1962 of the blood stem cell by two other renowned OCI scientists, Drs. Ernest McCulloch and James Till -- a discovery that formed the basis of all current stem cell research. Dr. Dick, who holds the Canada Research Chair in Stem Cell Biology and is also Senior Scientist at the Toronto General Research Institute and at the McEwen Centre for Regenerative Medicine, University Health Network, recently published other findings showing that colon cancer arises from stem cells specific to the tumour.
