In the present investigation, an innovative all-biomass solid facial mask was developed using electrospinning technology to incorporate naturally effective ingredients into bio-based fibers made of gelatin and pullulan polysaccharide. This process produced a nanofiber-based, fast-dissolving facial mask with essence uniformly embedded throughout the fibers. Unlike traditional facial masks that rely on preservatives, this solid mask avoids their use while offering excellent water and moisture retention. Owing to its nanostructured architecture and water-soluble fiber materials, it dissolves completely in water within just 7 s. Yak skin collagen peptides incorporated into the nanofiber film demonstrated strong antioxidant activity, scavenging 88.3% of DPPH free radicals. Biocompatibility testing combined with animal skin and eye irritation testing further confirmed the safety of the facial mask. This innovative approach not only supports the sustainable development of environment and resources but also delivers safer, more effective skincare solutions for consumers.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":640,"journal":{"name":"Journal of Leather Science and Engineering","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://JLSE.SpringerOpen.com/counter/pdf/10.1186/s42825-025-00204-x","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145169808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the marine environment with ultra-low uranium concentrations, high salinity, and microbial activity poses significant extraction challenges, compounded by selectivity and cost limitations in current methods. In the present investigation, an anti-biofouling amino oxime-functionalized collagen/sodium alginate aerogel (CF-AO/SA) was fabricated using leather waste-derived collagen. The dual cross-linked CF-AO/SA network, enhanced by Zn²⁺ incorporation, showed improved structural stability and antibacterial properties, as well as high uranium adsorption capacity, selectivity, and reusability. It achieved 320.7 mg g⁻¹ in 14 ppm uranium solution and maintained 78.6% removal efficiency after five cycles. Additionally, the removal rate of uranium was 89% in simulated seawater. Field tests in Zhuhai's Jinwan District (113.35° E, 21.99° N) showed 5.16 mg g⁻¹ uranium adsorption and excellent mechanical strength after 30 days in seawater. Furthermore, the production cost of CF-AO/SA was estimated at $3.652 per kilogram, which is lower than other reported adsorbents. The newly developed bio-based aerogel beads have substantial potential for practical applications for uranium capture in seawater and provide a novel high-value utilization way for leather wastes.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":640,"journal":{"name":"Journal of Leather Science and Engineering","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://JLSE.SpringerOpen.com/counter/pdf/10.1186/s42825-025-00201-0","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145162250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its progressive depletion has been closely associated with structural deterioration of the dermis and the visible signs of skin aging. Among current therapeutic strategies, the injection of exogenous collagen has been established as an effective method for alleviating aging-related skin changes. In the present study, a comprehensive evaluation was conducted to assess the injectability, cellular interactions, and photoaging repair efficacy of recombinant human collagen type III (RHC). The RHC solution was found to demonstrate favorable injectability and support the adhesion and chemotactic behavior of L929 cells, while also upregulating the expression of type I and type III collagen. In co-culture systems with lipopolysaccharide-stimulated macrophages, RHC treatment suppressed macrophage proliferation and reduced the production of proinflammatory cytokines, suggesting notable immunomodulatory properties. Upon intradermal injection of RHC into photoaged rat skin, an increased density of dermal collagen fibers was observed, accompanied by a more organized and uniform fiber arrangement. Additionally, hydroxyproline content and the expressions of collagen I and III were markedly elevated in the RHC group compared with the control and hyaluronic acid groups. Collectively, these findings suggest that RHC holds considerable promise as a therapeutic agent for both medical and cosmetic purposes targeting the restoration and maintenance of youthful skin characteristics.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":640,"journal":{"name":"Journal of Leather Science and Engineering","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://JLSE.SpringerOpen.com/counter/pdf/10.1186/s42825-025-00203-y","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145160928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the existing fillers for soft tissue augmentation have shown certain limitations in repairing mid-facial depression. Therefore, we herein report the development of a novel recombinant humanized type III collagen gel (C3Gel) through rational design and modification of a commercially available recombinant type III humanized collagen lyophilized fiber product. Both biological activity and tissue repair mechanisms of C3Gel were systematically evaluated in vitro and in vivo. C3Gel formed a dense fibrous structure around cells, significantly improving the ECM environment and providing strong support for cells, thereby promoting cell adhesion, migration, and proliferation. After injection of C3Gel into the dorsal region of rats, we observed a significant increase in the expression of type I collagen and elastin that improved tissue mechanical properties and elasticity. High-throughput RNA sequencing analysis revealed that C3Gel activated the integrin signaling pathway to improve binding between cells and ECM, resulting in the increased expression of downstream genes by activating the PI3K-Akt pathway which promoted the production of ECM components, such as collagen and laminin. At the same time, the expression of matrix metalloproteinases was inhibited to maintain ECM stability. Moreover, C3Gel is not carcinogenic in mice. Therefore, C3Gel demonstrates excellent biocompatibility and significant tissue repair ability, offering a safe, efficient, and long-term stable solution for mid-facial soft tissue augmentation, while providing new insights for other applications in regenerative medicine.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":640,"journal":{"name":"Journal of Leather Science and Engineering","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://JLSE.SpringerOpen.com/counter/pdf/10.1186/s42825-025-00196-8","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145160847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among ECM components, collagens stand out as key regulators of cell movement. However, existing reviews have provided only limited perspectives on the role of collagen-based biomaterials in directing migration across different cell populations. This gap in knowledge hinders a comprehensive understanding of collagen’s full potential. Drawing from systematic literature and our ongoing research, this review aims to summarize advancements over the past five years in the application of collagen-based biomaterials for modulating cell migration.
