Study Notes
Early Life and Education
- James Till was born and raised in Lloydminster, Saskatchewan, Canada.
- Earned a scholarship to study physics at the University of Saskatchewan
- Till obtained a PhD in biophysics from Yale University in 1957
Professional Career
- Till became a research fellow at the University of Toronto after completing his PhD
- In 1958, he partnered with Ernest McCulloch at the Ontario Cancer Institute for research
- Till's focus shifted to cancer treatment, research ethics, patient quality of life, and the Internet's role in supporting patients
Contributions and Discoveries
- Till and McCulloch co-authored a paper in 1961 outlining the susceptibility of mouse bone marrow cells to radiation.
- This discovery led to further exploration of stem cells
- Their research unveiled the existence of undifferentiated cells, now known as adult stem cells, residing in the inner marrow.
- These adult stem cells can transform into any type of blood cell
Recognition
- Till was recognized as a Fellow of the Royal Society of Canada in 1969
