- Canadian Ernest McCulloch was a hematologist who wanted to find a cure for leukemia
- He recognized the odd results of a radiation experiment as something new
- McCulloch was born and raised in Toronto
- He studied medicine at Toronto University and qualified as a doctor in 1948
- He returned to Toronto after a period at the Lister Institute (a medical research charity in London, UK)
- He worked as a research fellow in pathology at Sunnybrook Hospital
- In 1957, he joined the newly created Ontario Cancer Institute, a research division of Princess Margaret Hospital
- He began researching blood formation
- McCulloch soon joined forces with James Till
- Their work on stem cells transformed cancer research and gave rise to regenerative medicine
- McCulloch was a key figure in Canadian medical research
- He served on many national and international advisory committees
Milestones - Ernest McCulloch
- Became Head of Hematology at the Ontario Cancer Institute in 1957
- Published stem cell research findings with Till and Andrew Becker in Nature in 1963
- Focused his stem cell research on analyzing the mechanisms of human leukemia in the 1970s
- Inducted into the Canadian Science and Engineering Hall of Fame in 2010 along with Till
Milestones - James Till
- Declined an assistant professorship at Yale in 1957, in favor of a post at the University of Toronto
- Published a paper on the "radiation sensitivity of mouse bone marrow cells" with McCulloch in 1961
- Became a Fellow of the Royal Society of Canada in 1969
- Presented with the Albert Lasker Award for Basic Medical Research in 2005, jointly with McCulloch
- Physicist James Till turned his attention to cancer research
- He and Ernest McCulloch made the discovery of stem cells while working on radiation treatment
- James Till studied physics at the University of Saskatchewan via scholarship
- He completed a PhD in biophysics at Yale University in 1957
- In 1958, he began work with McCulloch at the Ontario Cancer Institute
- Till's research interests expanded in relation to cancer treatment later in his career
- His studies included research ethics and patient quality of life, as well as the role of the internet in patient advocacy and support
- McCulloch and Till discovered that most bones of the human body contain unspecialized cells called adult stem cells
- These cells reside in the inner marrow, and are able to develop into any blood cell
