Abstract All cells release small extracellular vesicles (EVs) that can carry cargo to other cells to affect their function. Mesenchymal stromal cells (MSCs) release EVs that have regenerative activities in vitro and in vivo and which represent potentially valuable new therapeutics. The realization of this potential is hindered by a lack of analytical methods to characterize MSC EVs, determine their mechanisms of action, and establish potency and dosage criteria. We will produce high resolution analysis tools for MSC EVs that will address these limitations and enable their development as new therapeutic entities.

摘要 所有细胞都释放小的细胞外囊泡（EV），这些囊泡可以将货物运送到其他细胞， 它们的功能。间充质基质细胞（MSC）释放具有再生活性的EV 其代表了潜在有价值的新治疗剂。实现 这种潜力受到缺乏分析方法来表征MSC EV， 其作用机制，并建立效力和剂量标准。我们将生产高 解决方案分析工具的MSC电动汽车，将解决这些限制，并使他们的 开发新的治疗实体。
