Wnt7a treatment ameliorates muscular dystrophy

Duchenne muscular dystrophy (DMD) is a devastating genetic muscular disorder of childhood marked by progressive debilitating muscle weakness and wasting, and ultimately death in the second or third decade of life. Wnt7a signaling through its receptor Fzd7 accelerates and augments regeneration by stimulating satellite stem cell expansion through the planar cell polarity pathway, as well as myofiber hypertrophy through the AKT/mammalian target of …
