Abstract on aging skeletal muscle stem cells and proposed rejuvenation perspectives
This abstract describes how skeletal muscle stem cells, called satellite cells, decline in number and function with age, partly through changes in their local and systemic environment, and outlines single-cell omics findings and future perspectives on rejuvenating interventions. [1]
Automatic summary · not editorially reviewed
The key findings
In skeletal muscle, resident stem cells called satellite cells decline in number and function with age, leading to loss of regenerative capacity. [1]
Aged satellite cells lose the capacity to preserve quiescence or to activate and expand upon injury, partly due to changes in the local and systemic environment. [1]
The authors discuss single-cell omics results on satellite cell and niche cell interactions and present future perspectives on rejuvenating interventions. [1]

Aged satellite cells and muscle regeneration
The abstract states that stem cells are central for tissue homeostasis and regeneration after stress and depend on interactions with neighboring niche cells. In skeletal muscle, the resident stem cells, also called satellite cells, decline in number and function with age. This leads to loss of regenerative capacity and eventually to deterioration of muscle integrity and physiology. Aged satellite cells lose the capacity to preserve quiescence or to activate and expand upon injury, partly due to changes in the local and systemic environment.

Single-cell omics on stem cell niche signals
The authors focus on age-associated intrinsic changes of satellite cells and the causes of their cellular and molecular decline. They discuss results from single-cell omics technologies that have shed light on interactions between satellite cells and niche cells and on how far-reaching signals impact satellite cell function. The abstract does not report specific results, sample sizes or measured outcomes from these technologies.

Proposed rejuvenation perspectives remain open questions
The abstract presents future perspectives on rejuvenating interventions to counter age-dependent regenerative decline and names open questions in muscle stem cell aging. These are described as perspectives and open questions, not as tested or established treatments. The abstract does not report whether any intervention was tested, in which population, or with which outcomes.
