间充质干细胞(MSC)疗法有望建立一个新的临床模式;然而,最近的试验产生了混合的结果。虽然MSC最初被认为是治疗结缔组织缺陷,但临床前研究揭示了有效的免疫调节特性,促使MSC用于治疗许多炎症性疾病。不幸的是,尽管临床试验达到了安全性终点,但疗效尚未得到证实。我们认为,证明疗效的挑战部分归因于对MSC输注后命运的不完全理解。在这里,我们强调了MSC治疗的临床地位,并讨论了细胞跟踪技术的重要性,这提高了我们对全身输注MSC的命运和功能的理解,并可能提高临床应用。
Mesenchymal stem cell (MSC) therapy is poised to establish a new clinical paradigm; however, recent trials have produced mixed results. Although MSC were originally considered to treat connective tissue defects, preclinical studies revealed potent immunomodulatory properties that prompted the use of MSC to treat numerous inflammatory conditions. Unfortunately, although clinical trials have met safety endpoints, efficacy has not been demonstrated. We believe the challenge to demonstrate efficacy can be attributed in part to an incomplete understanding of the fate of MSC following infusion. Here, we highlight the clinical status of MSC therapy and discuss the importance of cell-tracking techniques, which have advanced our understanding of the fate and function of systemically infused MSC and might improve clinical application.
