骨不连是骨科领域中一个复杂且具有挑战性的问题,影响患者生活质量。间充质干细胞(mesenchymal stem cells,MSCs)因其自我更新能力和多向分化潜能,在促进骨修复和再生中显示出巨大潜力。本文总结了MSCs在骨不连治疗中的作用机制,包括其成骨分化潜能、通过分泌生物活性因子促进血管生成和调节炎症反应的能力,以及其免疫调节功能。论述了MSCs的来源选择、扩增与制备方法、干预方式及剂量,并强调了个体化和精准化治疗的重要性。此外,还总结了MSCs递送的生物材料、“启动”MSCs以增强其功能,以及MSCs分泌体在治疗中的关键作用。尽管MSCs治疗的安全性和有效性得到了证实,但现有研究的异质性限制了对MSCs治疗最佳实践的确定。本文为MSCs在骨不连治疗中的应用提供了科学依据,以期推动MSCs治疗策略的优化和临床转化。
Nonunion fractures is a complex and challenging issue in orthopedics that affects the quality of life of patients. Mesenchymal stem cells(MSCs) have shown great potential in promoting bone repair and regeneration due to their self-renewal capacity and multipotent differentiation potential. This article summarizes the mechanisms of action of MSCs in the treatment of nonunion fractures,including their osteogenic differentiation potential,the ability to promote angiogenesis and modulate inflammatory responses through the secretion of bioactive factors,and their immunomodulatory functions. In terms of therapeutic strategies,we discuss the selection of MSC sources,expansion and preparation methods,intervention modes,and dosages,emphasizing the importance of personalized and precision treatments. Furthermore,we describe the biomaterials for MSC delivery,“priming” MSCs to enhance their functions,and the key role of MSC-derived secretomes in therapy. Although the safety and efficacy of MSC therapy have been confirmed,the heterogeneity of existing studies limits the determination of best practices for MSC-based treatments. This review provides a scientific rationale for the application of MSCs in the treatment of nonunion fractures,with the aim of promoting the optimization and clinical translation of MSC-based therapeutic strategies.
