The Till & McCulloch Award

Drs. James Till and Ernest McCulloch
In 2005, SCN inaugurated the Till & McCulloch Award in honour of Canadian scientists James Till and Ernest McCulloch, whose pioneering work established the field of stem cell research. The Till & McCulloch Award is presented annually to one researcher in Canada in recognition of their exceptional contributions to global stem cell research in that year.
Researchers are nominated through a public process, and the Selection Committee chooses the awardee based on what is determined to be the year’s most influential peer-reviewed article by a stem cell researcher working in Canada.
The award is presented at the annual Till & McCulloch Meetings and is accompanied by the delivery of the Till & McCulloch Lecture.
Dr. Gordon Keller receives the 2023 Till & McCulloch Award for his research focused on heart development and stem-cell derived heart cell subtypes
Dr. Gordon Keller, Director of the McEwen Stem Cell Institute, Senior Scientist at the Princess Margaret Cancer Centre, and Professor in the Department of Medical Biophysics at the University of Toronto has been named the 2023 Till & McCulloch Award recipient. He is recognized for his paper published in Cell Stem Cell entitled, Modeling human multi-lineage heart field development with pluripotent stem cells.
Dr. Keller will accept his award and present the Till & McCulloch Award lecture on October 24 at the 2023 Till & McCulloch Meetings in Toronto.

The Drew Lyall Award of Excellence

Drew Lyall
Drew Lyall was the inaugural executive director of the Stem Cell Network and, over 12 years, helped build it into an internationally respected research and development powerhouse. He died in January 2016, in Ottawa, a few days shy of his 50th birthday after an eight-year battle with melanoma.
To honour Drew’s memory, and to recognize his legacy, in 2016 SCN inaugurated the Drew Lyall Award of Excellence. This award is presented annually at the Till & McCulloch Meetings to the lead author of the highest ranked abstract in the abstract competition, and is accompanied by the delivery of the Drew Lyall Award of Excellence talk.
Dr. Murtaza Nagree is the recipient of the 2023 Drew Lyall Award of Excellence, for the highest-ranked abstract in the TMM2023 abstract competition.
He is recognized for his work as lead author on A hematopoietic stem cell subset that retains memory of prior inflammatory stress accumulates in aging and clonal hematopoiesis.
Dr. Nagree is a Postdoctoral Fellow in the John Dick Lab at the University Health Network who has been working with Andy Zeng under the supervision of Dr. Stephanie Xie to unravel how blood stem cells react to and remember inflammation.
Dr. Nagree will accept his award and present the Drew Lyall Award of Excellence talk on October 24 at the 2023 Till & McCulloch Meetings in Toronto.
