The first in a series of short (around 1 minute) animated films that answer basic questions about stem cell research.
A seminal paper published in 1961 by Drs. James Till and Ernest McCulloch was the first academic study to prove the existence of an exciting new type of cell, the stem cell. Since this foundational study, the promise of stem cells and their application to human disease has grown tremendously, their potential only beginning to be realized. This animated video, narrated by Dr. Till, provides a brief explanation of this early study as well as explaining the two basic concepts that define the answer to the question "What is a stem cell?"
