Pioneers in Science:听 Drs. Yves Clermont and Charles Leblond
听
By observing the steps of sperm differentiation in the testis as well as the population of spermatogonia responsible for the production of spermatozoa, the Renewal of Spermatogonia in the Rat revealed the first identified population of stem cells and included the first use of the term "stem cells" in this biological context.
This ground-breaking discovery--the subsequent applications of which have helped combat human diseases ranging from cancer to degenerative conditions--paved the way for a revolution in science.听 We are proud to have been the home of two such illustrious Canadian pioneers in science.

"I had the exceptional privilege of being taught by Drs. Clermont and Leblond. 
As medical students, we had no idea that the two gentlemen who taught us histology with such grace and flair, were pioneering scientists who had made the fundamental observations that laid the groundwork for stem cell biology. Yet, perhaps we should have guessed from their mastery of the subject and their deep understanding of biology. It is most fitting that we celebrate these two gifted researchers whose work opened the door to an entirely new branch of medical science.鈥�

"It is very appropriate that, with the enormous current interest in induced pluripotency stem cells by Dr. Yamanaka and colleagues, we should be reminded of the history of the stem cell concept. The paper by Clermont and Leblond (1953) on spermatogonia renewal in the rat is certainly a landmark paper in this field."

鈥淐lermont and Leblond鈥檚 beautiful study of how sperm develop in the testis laid out many of the underlying principles that still drive modern stem cell biology. A great contribution from two great Canadian scientists.鈥�

鈥淚 have recently discovered 鈥揳nd eagerly read many of the ground-breaking papers of C.P. Leblond on stem cells. I have come to conclude that with all of today鈥檚 technologies we only confirm the concepts that Leblond laid down over half a century ago.鈥�

鈥淧rofessor Charles Leblond鈥檚 pioneering studies in stem cell biology, beginning with the landmark report of spermatogonia self renewal in 1953, heralded Canada鈥檚 preeminent role and current international standing in this critical field of medicine. As a 麻豆AV alumnus, I am truly grateful to have had the opportunity to follow the footsteps of this scientific giant and be part of the great Canadian stem cell legacy he created.鈥�
