Immunohistochemical staining of myosin heavy chain isoforms has emerged as the state-of-the-art discriminator of skeletal muscle fiber-type (i.e., type I, type IIA, type IIX, type IIB). Here, we present a staining protocol along with a novel semi-automated algorithm that facilitates rapid assessment of fiber-type and fiber morphology.

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.

To assess the in vivo effects of therapeutic interventions for muscle disease, methods are needed to quantitate force generation and fatigability in treated muscle. We detail an approach to evaluating myo-mechanical properties in explanted mouse hindlimb muscle. This analysis provides a robust approach to quantitating the effects of genetic modification on muscle function, as well as comparison of therapies in mouse models of muscle disease.

This protocol aims to isolate and purify skeletal muscle interstitial extracellular vesicles (SkM-EVs) from rodent muscle tissues through mechanical detachment, enzymatic dissociation, filtration, and differential ultracentrifugation. It demonstrates consistency and reliability. The isolated SkM-EVs provide insights into muscle homeostasis and diseases, with potential applications as diagnostic biomarkers or therapeutic vehicles.

We describe a protocol to obtain enzymatically dissociated fibers of different lengths and types from six muscles of adult mice: three of them already described (flexor digitorum brevis, extensor digitorum longus, soleus) and three of them successfully dissociated for the first time (extensor hallucis longus, peroneus longus, peroneus digiti quarti).
FAQs
The predominance of slow-twitch fibers makes sustained output a central interpretive feature. During Soleus Muscle Analysis, researchers can therefore examine how activation relates to posture, endurance, and locomotion rather than treating every contraction as equivalent. This fiber profile helps frame changes in activity as evidence about neural regulation of prolonged lower-limb force, especially during standing or repeated movement.
Comparing soleus activation between standing, gait, or other movement conditions shows how control changes with behavioral demand. Higher or lower activity can be interpreted alongside the task rather than in isolation, helping distinguish muscle responses associated with posture, locomotion, endurance, or motor adaptation. Comparisons across experimental groups similarly connect altered activation patterns with differences in observable lower-limb behavior.
Electromyography, contractile force, and muscle morphology provide complementary perspectives. Electromyography indicates activation, force assessment addresses contractile output, and morphology describes structural characteristics. Using more than one measure can help relate neural control to the muscle’s mechanical performance and physical organization. This combination is useful when a behavioral change might reflect altered activation, output, structure, or some relationship among them.
A basic workflow begins by choosing a soleus measure that matches the behavioral question, such as electromyography for activation, force for contractile output, or morphology for structure. Researchers then examine the measure during standing or movement and compare results across tasks, conditions, or groups. Interpreting these results with balance, gait, endurance, or adaptation links muscle data to behavior.
The choice depends on the aspect under study. Electromyography is appropriate for activation, contractile-force assessment for output, and morphology for structural features. If the question concerns how neural control supports a behavior, activation may be central; if it concerns muscle performance or organization, force or morphology adds the more direct outcome. Selecting the measure this way keeps the analysis aligned with the research question.
By measuring soleus responses across tasks or conditions, investigators can track changes in lower-limb muscle activity while behavior changes. These comparisons help connect neural regulation with balance, gait, endurance, and adaptation. The approach is especially informative when the goal is to explain how sustained muscle output contributes to observable actions or differs between experimental groups.
