Unleashing Potential Stem Cells


James Till and Ernest McCulloch were studying the effect of radiation on the bone marrow of mice when they discovered the existence of hematopoietic stem cells, the precursor to all other blood cells. Known as the fathers of stem cell science, their work revolutionized cell biology and cancer therapy. They would go on to train a generation of researchers at the University of Toronto who built on their work to create improved treatments for a variety of illnesses.

Till and McCulloch’s discovery led to life-saving bone marrow transplants in leukemia patients.
