James Till: A Pioneer in Stem Cell Research

Born in Lloydminster, Saskatchewan, Canada, in 1931.
Received a scholarship to the University of Saskatchewan to study physics, later completing a PhD in biophysics from Yale University in 1957.
After a research fellowship at the University of Toronto, he joined the Ontario Cancer Institute in 1958, collaborating with Ernest McCulloch.
He was recognized for his groundbreaking contributions to stem cell research, receiving the Albert Lasker Award for Basic Medical Research in 2005.
He was inducted into the Canadian Science and Engineering Hall of Fame.

Stem Cell Discovery

McCulloch and Till discovered that most bones contain unspecialized cells called adult stem cells, residing in the bone marrow.
These cells have the potential to develop into any type of blood cell.
Their discovery was published in the scientific journal Nature in 1963.
