    "body_text": "University of Pennsylvania researchers found that removing TRF2 from muscle stem cells caused them to lose their defining identity instead of simply dying. Injured mouse muscle then regenerated poorly and accumulated scar and fatty tissue; removing the protein also accelerated disease in a Duchenne muscular dystrophy model. The findings are mechanistic mouse results, not a treatment tested in people.",
