A translational study reported that muse cells, a class of pluripotent stem cells found in adult tissues, reduced neurodegeneration in Parkinson’s disease models. The investigators documented neuroprotective effects, functional improvements and indications of cell integration in preclinical systems. The paper positions muse cells as an alternative regenerative approach that may avoid some limitations of induced pluripotent stem cells, but authors emphasize the need for controlled clinical evaluation and long‑term safety monitoring.
