摘要
目的：我们的荟萃分析旨在评估基因修饰干细胞治疗在临床前骨质疏松症模型中的疗效。方法：我们在PubMed， Embase， Web of Science和Cochrane Library数据库中进行了从成立到2023年9月15日的全面文献检索。我们使用随机效应模型对转基因干细胞治疗对骨质疏松症动物的影响进行了汇总分析。主要结果包括骨矿物质密度（BMD）和骨体积分数。(BV /电视)。所有meta分析均采用Cochrane Collaboration的Review Manager（5.3版）和Stata 15.0统计软件进行。结果：共纳入文献2567篇，其中符合纳入标准的文献16篇。其中，13项研究评估了BMD， 11项研究评估了BV/TV。与对照组相比，转基因干细胞治疗显著改善了BMD（标准化平均差[SMD] = 1.85, 95%可信区间[CI]: 1.06-2.63, P 2 = 69%）和BV/TV（标准化平均差[SMD] = 2.11, 95%可信区间[CI]: 1.10-3.12, P 2 = 78%）。结论：基因修饰干细胞治疗是一种安全有效的方法，可显著改善骨质疏松动物模型的BMD和BV/TV。这些结果为今后基因修饰干细胞的临床转化研究提供了重要的基础。
Genetically modified stem cells for osteoporosis: a systematic review and meta-analysis of preclinical studies.
Objective: Our meta-analysis aims to assess the efficacy of genetically modified stem cell therapy in preclinical osteoporosis models.
Methods: We executed a thorough literature search across PubMed, Embase, Web of Science, and the Cochrane Library databases from inception to September 15, 2023. We used a random-effect model for pooled analysis of the effect of genetically modified stem cell therapy on animals with osteoporosis. The primary outcomes included bone mineral density (BMD) and bone volume fraction. (BV/TV). All meta-analyses were performed employing the Cochrane Collaboration's Review Manager (version 5.3) in conjunction with Stata 15.0 statistical software.
Results: A total of 2567 articles were reviewed, of which 16 articles met inclusion criteria. Of these, 13 studies evaluated the BMD and 11 studies evaluated BV/TV. Compared to the control group, genetically modified stem cell therapy was associated with significantly improved BMD (standardized mean difference [SMD] = 1.85, 95% Confidence Interval [CI]: 1.06-2.63, P < 0.001, I2 = 69%) and BV/TV (standardized mean difference [SMD] = 2.11, 95% Confidence Interval [CI]: 1.10-3.12, P < 0.001, I2 = 78%).
Conclusion: Genetically modified stem cell therapy is a safe and effective method that can significantly improve the BMD and BV/TV in animal models of osteoporosis. These results provide an important basis for future translational clinical studies of genetically modified stem cells.
期刊介绍：
BMC Musculoskeletal Disorders is an open access, peer-reviewed journal that considers articles on all aspects of the prevention, diagnosis and management of musculoskeletal disorders, as well as related molecular genetics, pathophysiology, and epidemiology.
The scope of the Journal covers research into rheumatic diseases where the primary focus relates specifically to a component(s) of the musculoskeletal system.
