Skeletal muscle regeneration is driven by tissue resident muscle stem cells, which are impaired in many muscle diseases such as muscular dystrophy, and this results in the inability of muscle to regenerate. Here, we describe a protocol that allows the examination of muscle regeneration in zebrafish models of muscle disease.

In this report we describe a method to crush mouse sciatic nerve. This method uses readily available hemostatic forceps and easily and reproducibly produces complete sciatic nerve crush. In addition, we describe a method to prepare muscle whole mounts suitable for analysis of nerve regeneration after sciatic nerve crush.

Induced pluripotent stem cell (iPSC)-derived myogenic progenitors are promising candidates for cell therapy strategies to treat muscular dystrophies. This protocol describes transplantation and functional measurements required to evaluate the engraftment and differentiation of iPSC-derived mesoangioblasts (a type of muscle progenitors) in mouse models of acute and chronic muscle regeneration.

An Introduction to Aging and Regeneration
0 Views •
2023
Tissues are maintained through a balance of cellular aging and regeneration. Aging refers to the gradual loss of cellular function, and regeneration is the repair of damaged tissue generally mediated by preexisting adult or somatic stem cells. Scientists are interested in understanding the biological mechanisms behind these two complex processes. By doing so, researchers may be able to use somatic stem cells to treat degenerative diseases and develop therapies that could delay the effects of...

This manuscript describes a detailed protocol to induce acute skeletal muscle regeneration in adult mice and subsequent manipulations of the muscles, such as dissection, freezing, cutting, routine staining, and myofiber cross-sectional area analysis.
FAQs
Satellite cells connect injury signals with tissue rebuilding. In response to inflammatory signals, these resident muscle stem cells leave quiescence, their resting state, and proliferate before differentiating into myoblasts. The resulting cells can fuse with existing muscle fibers or contribute to new ones, linking cellular activation with restoration of muscle structure and function.
Immune cells and growth factors participate in the coordinated environment that follows muscle injury. Inflammatory signals help activate satellite cells, while the broader response includes interactions among resident stem cells, immune components, growth factors, and the extracellular matrix. Studying these relationships helps explain why regeneration depends on coordinated tissue responses rather than one cell type alone.
Extracellular matrix remodeling is one component of the tissue response that accompanies muscle regeneration. Because repair must restore both structure and function, changes in the matrix are considered alongside satellite-cell activity, immune involvement, and growth-factor signaling. This integrated view helps researchers examine regeneration as a coordinated biological process rather than an isolated stem-cell event.
Muscle regeneration provides a biological context for studying how skeletal muscle responds to exercise. Research can connect repair-related activity with the broader ability of muscle tissue to maintain or restore structure and function. This relationship makes regeneration relevant not only after obvious injury, but also to investigations of how muscle adapts in exercise-focused biology.
The field is relevant to several distinct muscle challenges, including traumatic injuries, muscular dystrophies, and aging-related muscle loss. These conditions create different research contexts for examining how repair responses affect tissue structure, function, strength, and recovery. Considering them together allows investigators to identify broad regenerative principles while addressing clinically and biologically different problems.
Research on muscle regeneration can inform therapies designed to improve strength and recovery. Investigators can use knowledge of satellite-cell activation, immune participation, growth-factor involvement, and extracellular-matrix remodeling to understand which parts of the repair response may be relevant to intervention. The ultimate application is improving restoration of muscle performance after damage or disease.
