Intramuscular Injection of Mesenchymal Stem Cells Activates Anabolic and Catabolic Systems in Mouse Skeletal Muscle

Researchers measured changes in mechanistic target of rapamycin complex 1 signaling, the ubiquitin–proteasome system, and autophagy-lysosome system-related factors after a single intramuscular injection of MSCs with green fluorescence protein into mouse muscles.
