Muscle stem cell engraftment and differentiation (None standard; SC engraftment and differentiation, MuSC engraftment, MPC engraftment are seen in the literature but not as formalized abbreviations)

Muscle stem/progenitor cell engraftment and differentiation is a process wherein muscle stem cells (primarily satellite cells, SCs) and committed myogenic progenitor cells are transplanted or mobilized to damaged or diseased skeletal muscle, with the aim of regenerating functional muscle tissue. Successful engraftment requires proliferative expansion, migration to the injury site, differentiation into myoblasts and subsequently myofibers, and integration into the existing muscle architecture. This process is regulated by numerous growth factors (FGF, HGF, IGF), transcription factors (Pax7, MyoD, Myf5), cell-ECM interactions, and signals from the regenerative niche (macrophages, fibrogenic cells, chemokines such as SDF-1/CXCR4). While promising for therapeutic development in muscular dystrophies and muscle injuries, clinical translation faces challenges including immune compatibility, integration efficiency, and robust functional recovery.
