The anti-aging effects of exercise, without exercise: Self-contracting muscle implants give mice a boost

What the research found
Study (mice). Liu, Yao, Ng Shyh-Chang and colleagues report in Nature Aging that about 6 million matured autologous myocytes injected under the skin formed vascularized “myografts” that flexed on their own for at least 81 days. In aged and obese mice the grafts tracked with more lean mass, grip, running endurance, bone density, lower inflammation, and better maze scores. This is preclinical cell therapy, not a gym replacement and not a supplement. Human safety is unproven.
Evidence level: Animal study. Results in animals or cells often don't carry over to people.
