From an article about the study published in the June 5 issue of Cell Stem Cell:

Scientists at the Ottawa Hospital Research Institute (OHRI) and the University of Ottawa have discovered a powerful new way to stimulate muscle regeneration, paving the way for new treatments for debilitating conditions such as muscular dystrophy…

Satellite stem cells are specialized muscle stem cells that live in adult skeletal muscle tissue and have the ability to both replicate and differentiate into various types of muscle cells. Dr. Rudnicki’s team found that the Wnt7a protein, when introduced into mouse muscle tissue, significantly increased the population of these satellite stem cells and fueled the regeneration process, creating bigger and stronger muscles. Muscle tissue mass was increased by nearly 20 per cent in the study.
