Scientists move one step closer to producing blood-forming stem cells
Stem cell scientists have moved one step closer to producing blood-forming stem cells in a Petri dish by identifying a key regulator controlling their formation in the early embryo, shows research published online today in Cell.
The work was reported by Dr. Gordon Keller, Director of the McEwen Centre for Regenerative Medicine, and Senior Scientist at Princess Margaret Cancer Centre, both at University Health Network. Dr. Keller is also Professor in the Department of Medical Biophysics at the University of Toronto and holds a Canada Research Chair in stem cell biology.
Using mouse models to study the process of blood cell development, Dr. Keller and his team demonstrated that the retinoic acid signalling pathway is required for formation of blood-forming stem cells. Retinoic acid is produced from vitamin A and is essential for many areas of human growth and development.
