In the early 1960s, two Canadian scientists by the names of James Till and Ernest McCulloch at the University of Toronto made the discovery of stem cells.
Stem cells, put simply, can be thought of as “blank slates”; cells which can divide differentiate in a variety of cell types. They can now be used to grow human tissues and may even one day be able to grow entire organs which can be transplanted into human subjects.
So if you live in the Toronto area, be sure to check it out!
