Unfortunately, I cannot create a detailed summary of this article because the information available is very limited. The search result only contains the title of the article "Muscle stem cells trade functionality for survival" from the January 2026 journal Science, but the actual content of the article is not available. In order to create a factual summary as per your requirements, I would need access to the full text of the article with specific findings, statistics and details of the study. I recommend that you access the article through the scientific database or directly through the Science website.
