We have developed an SET module for our large animal model of ischemic myopathy. We hypothesized that SET would increase muscle strength and walking distance in this model.

Terminal muscle samples were used for skeletal muscle testing. <b>Results:</b> SET animals increased walking distance over time. SET increased muscle strength in both the ischemic and nonischemic limb.

Existing therapies, such as autologous muscle transfer and physical therapy, are incapable of returning full function and force production to injured muscle. <b>Recent Advances:</b> Skeletal muscle tissue constructs may provide an alternative to existing therapies currently used to treat VML. Unlike autologous muscle transplants, muscle constructs can be cultured <i>in vitro</i> and are not reliant on intact muscle tissue. Skeletal muscle constructs can be generated from small muscle biopsies and could be used to generate skeletal muscle tissue constructs to replace injured tissues. <b>Critical Issues:</b> To serve as effective therapies, muscle constructs must be capable of generating contractile forces that can assist the function of host skeletal muscle. The contractile force of native muscle arises in part as a consequence of the highly aligned, bundled architecture of myofibers. Attempts to induce similar alignment include applications of tension/strain across hydrogels, inducing aligned architectures within scaffolds, casting tissues in straited molds, and 3D printing. While all these methods have demonstrated efficacy toward inducing myofiber alignment, the extent of myofiber alignment, tissue formation, and force production varies. This manusript critically reviews the advantages and limitations of these methods and specifically discusses their ability to impart mechanical and architectural cues to induce alignment within tissue constructs. <b>Future Directions:</b> As tissue-synthesizing techniques continue to improve, muscle constructs must include more cell types than simply myoblasts, such as the addition of neuronal and endothelial cells. Higher-level tissue organization is critical to the success of these constructs. Many of these technologies have yet to be implanted into host tissue to understand engraftment and how they can contribute to traumatic injury, and as such continued collaboration between surgeons and tissue engineers is necessary to ultimately result in clinical translation.</p>","PeriodicalId":7413,"journal":{"name":"Advances in wound care","volume":" ","pages":"114-131"},"PeriodicalIF":5.8,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141911351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The preclinical findings of minimal irritation with SN514 were verified by a Phase 1 first-in-human 21-day cumulative skin irritation test. Irritation was observed to increase stepwise by concentration, confirming formulation accuracy. Each enzyme concentration was found to be \"possibly mild in use\" (Berger and Bowman method). No treatment emergent adverse events were observed during the study. <b>Innovation:</b> A fast-acting enzyme with a favorable irritation profile, prepared as a stable, ready to use hydrogel formulation, overcomes many recognized shortcomings of enzyme debriders. <b>Conclusion:</b> The overall findings support clinical dose range testing for tolerance and preliminary efficacy.</p>","PeriodicalId":7413,"journal":{"name":"Advances in wound care","volume":" ","pages":""},"PeriodicalIF":5.8,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143031754","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
