Twenty-five years have passed since the first clinical trial utilising mesenchymal stomal/stem cells (MSCs) in 1995. In this time academic research has grown our understanding of MSC biochemistry and our ability to manipulate these cells in vitro using chemical, biomaterial, and mechanical methods. Research has been emboldened by the promise that MSCs can treat illness and repair damaged tissues through their capacity for immunomodulation and differentiation. Since 1995, 31 therapeutic products containing MSCs and/or progenitors have reached the market with the level of in vitro manipulation varying significantly. In this review, we summarise existing therapeutic products containing MSCs or mesenchymal progenitor cells and examine the challenges faced when developing new therapeutic products. Successful progression to clinical trial, and ultimately market, requires a thorough understanding of these hurdles at the earliest stages of in vitro pre-clinical development. It is beneficial to understand the health economic benefit for a new product and the reimbursement potential within various healthcare systems. Pre-clinical studies should be selected to demonstrate efficacy and safety for the specific clinical indication in humans, to avoid duplication of effort and minimise animal usage. Early consideration should also be given to manufacturing: how cell manipulation methods will integrate into highly controlled workflows and how they will be scaled up to produce clinically relevant quantities of cells. Finally, we summarise the main regulatory pathways for these clinical products, which can help shape early therapeutic design and testing.

在治疗产品中难以吸收间充质干细胞及其祖细胞。

自1995年首次利用间充质造血/干细胞(MSC)进行临床试验以来,已经过去了25年。在这段时间里,学术研究已经使我们对MSC生物化学以及利用化学,生物材料和体外方法处理这些细胞的能力有了更深入的了解。机械方法。MSC可以通过其免疫调节和分化能力来治疗疾病和修复受损组织的承诺使研究更加鼓舞。自1995年以来,市场上有31种含有MSC和/或祖细胞的治疗产品,其体外操作水平差异很大。在这篇综述中,我们总结了包含MSC或间充质祖细胞的现有治疗产品,并研究了开发新治疗产品时面临的挑战。成功地进行临床试验,最终要进入市场,需要在体外​​临床前开发的最早阶段全面了解这些障碍。了解新产品对健康的经济利益以及各种医疗保健系统中的报销潜力是有益的。应该选择临床前研究来证明对人类特定临床适应症的功效和安全性,以避免重复劳动并最大程度地减少动物的使用。还应及早考虑制造:细胞操纵方法将如何整合到高度受控的工作流程中,以及如何扩大规模以生产临床上相关数量的细胞。最后,我们总结了这些临床产品的主要调控途径,可以帮助塑造早期的治疗设计和测试。需要在体外​​临床前开发的最早阶段全面了解这些障碍。了解新产品对健康的经济利益以及各种医疗保健系统中的报销潜力是有益的。应该选择临床前研究来证明对人类特定临床适应症的功效和安全性,以避免重复劳动并最大程度地减少动物的使用。还应及早考虑制造:细胞操纵方法将如何整合到高度受控的工作流程中,以及如何扩大规模以生产临床上相关数量的细胞。最后,我们总结了这些临床产品的主要调控途径,可以帮助塑造早期的治疗设计和测试。需要在体外​​临床前开发的最早阶段全面了解这些障碍。了解新产品对健康的经济利益以及各种医疗保健系统中的报销潜力是有益的。应该选择临床前研究来证明对人类特定临床适应症的功效和安全性,以避免重复劳动并最大程度地减少动物的使用。还应及早考虑制造:细胞操纵方法将如何整合到高度受控的工作流程中,以及如何扩大规模以生产临床上相关数量的细胞。最后,我们总结了这些临床产品的主要调控途径,可以帮助塑造早期的治疗设计和测试。
