The proliferation and differentiation of WJMSCs and Limbal Epithelial Stem Cells (LESCs) were investigated using MTT assays, real-time PCR and immunostaining.Results: The PRGF-loaded Co/SF scaffold significantly promoted the proliferation of both WJMSCs and LESCs in a concentration-dependent manner. Real-time PCR and immune staining revealed a significant increase in the expression of P63, ABCG2, and cytokeratin 3/12 markers in WJMSCs, a significant decrease in the expression of P63 and ABCG2, and a significant increase in the expression of cytokeratin 3/12 markers indicating successful differentiation into CECs.Conclusion: The WJMSC cultured on PRGF-enriched Co/SF scaffold demonstrates potential as a viable alternative to conventional CLET, offering a promising strategy for corneal tissue regeneration.","PeriodicalId":21043,"journal":{"name":"Regenerative medicine","volume":" ","pages":"1-12"},"PeriodicalIF":2.4,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142668803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this article is to highlight key findings from the database and put them into context within the global landscape and various initiatives intended to attract ATMP developers to the UK.Method: A targeted search of GlobalData's clinical trial database was performed, followed by refinement so that only trials investigating products meeting ATMP definitions were included, and that each trial was only counted once in the analysis.Results: The 2023 data show that the number of ongoing ATMP clinical trials in the UK has remained approximately static, in contrast to a 10% reduction reported globally. Approximately 80% of these trials were commercially sponsored. Although most ATMP clinical trials are early phase, there is evidence indicating progression to later phase studies.Conclusion: The data indicate that the UK remains an attractive region for ATMP clinical trials. Factors including UK government investment in research, regulatory support offered by MHRA, and the Advanced Therapy Treatment Centre (ATTC) network of clinical sites, may contribute to the positive ecosystem available to developers of ATMPs.","PeriodicalId":21043,"journal":{"name":"Regenerative medicine","volume":" ","pages":"1-8"},"PeriodicalIF":2.4,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142644688","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review examines key factors affecting outcomes. Age-related declines, like reduced nerve fiber density and impaired axonal transport of vesicles, hinder recovery. Hormonal differences influence regeneration, with BDNF/trkB critical for testosterone and nerve growth factor for estrogen signaling pathways. Species and strain selection impact outcomes, with C57BL/6 mice and Sprague-Dawley rats exhibiting varying regenerative capacities. Injury models - crush for early regeneration, chronic constriction for neuropathic pain, stretch for traumatic elongation and transection for severe lacerations - provide insights into clinically relevant scenarios. Repair techniques, such as nerve grafts and conduits, show that autografts are the gold standard for gaps over 3 cm, with success influenced by graft type and diameter. Time course analysis highlights crucial early degeneration and regeneration phases within the first month, with functional recovery stabilizing by three to six months. Early intervention optimizes regeneration by reducing scar tissue formation, while later interventions focus on remyelination. Understanding these factors is vital for designing robust preclinical studies and translating research into effective clinical treatments for peripheral nerve injuries.","PeriodicalId":21043,"journal":{"name":"Regenerative medicine","volume":" ","pages":"1-17"},"PeriodicalIF":2.4,"publicationDate":"2024-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142522848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
