In response to injury, satellite cells (SCs) asymmetrically divide to self-renew and repair muscle. Here the authors show that a cytokine G-CSF is crucial for long-term expansion of activated SCs and muscle regeneration in mice, suggesting that G-CSF treatment may have beneficial effect in Duchenne muscular dystrophy.
