Potential Obesity Treatment Emerges from Stem Cell Discovery

Ottawa scientists have identified a trigger that turns muscle stem cells into brown fat, a form of good fat that could play a critical role in the fight against obesity. The findings from Dr. Michael Rudnicki's lab, based at the Ottawa Hospital Research Institute, are published in the prestigious journal Cell Metabolism.

"This discovery significantly advances our ability to harness this good fat in the battle against bad fat and all the associated health risks that come with being overweight and obese," says Dr. Rudnicki, a senior scientist and director for the Regenerative Medicine Program and Sprott Centre for Stem Cell Research at the Ottawa Hospital Research Institute. He is also a Canada Research Chair in Molecular Genetics and professor in the Faculty of Medicine at the University of Ottawa.

Globally, obesity is the fifth leading risk for death, with an estimated 2.8 million people dying every year from the effects of being overweight or obese, according to the World Health Organization. The Public Health Agency of Canada estimates that 25% of Canadian adults are obese.

In 2007, Dr. Rudnicki led a team that was the first to prove the existence of adult skeletal muscle stem cells. In the paper published today, Dr. Rudnicki now shows (again for the first time) that these adult muscle stem cells not only have the ability to produce muscle fibres, but also to become brown fat. Brown fat is an energy-burning tissue that is important to the body's ability to keep warm and regulate temperature. In addition, more brown fat is associated with less obesity.
