This demonstrated superior outcomes with combination therapy against HA only at 3, 6, and 12 months on the visual acuity scale (VAS, p < 0.001), and with the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) at 12 months in areas of stiffness and physical function (p < 0.001). For combination therapy versus PRP alone, one randomized controlled trial qualified as best current evidence. This demonstrated superior VAS outcomes with combination therapy compared to PRP monotherapy at 6 months (p < 0.02).Conclusion: Best current evidence indicates that intra-articular HA and PRP as combination therapy has superior short and long term symptom control over HA or PRP as monotherapy. Due to the extensive heterogeneity in the studies, results should be interpreted with caution.","PeriodicalId":21043,"journal":{"name":"Regenerative medicine","volume":" ","pages":"637-644"},"PeriodicalIF":2.4,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142814128","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}

Since the publication of data forms an endpoint of the study, this review specifically focused on the published clinical trials done with EVs. For brevity, this review was restricted to the last 10 years. Unexpectedly, the literature search showed that very few clinical trials assessing the therapeutic applications of EVs were published in this period indicating that they have not reached their desired endpoint. Conversely, most studies showed the potential of EVs present in various biofluids as a promising source of diagnostic and prognostic biomarkers for various diseases, and predictive markers to assess the effectiveness of therapy. This stark difference in the numbers could perhaps be due to the time-consuming regulatory processes involved in the clinical-grade preparation and characterization of EVs, and the determination of their safety and effective dose regimens. One wonders whether fast-tracking regulatory affairs could help accelerate the therapeutic use of EVs. This aspect needs urgent attention.","PeriodicalId":21043,"journal":{"name":"Regenerative medicine","volume":" ","pages":"617-635"},"PeriodicalIF":2.4,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11730413/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142839087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","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":"561-577"},"PeriodicalIF":2.4,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11633413/pdf/","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":"OA","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.
