Altered stem cell homeostasis underlies functional tissue decline during muscle aging and disease progression. Janus kinase–signal transducer and activator of transcription (JAK-STAT) signal transduction is a crucial regulator of muscle regeneration, and targeting this pathway in mice relieves aspects of debilitating muscle wasting.
