Dental stem cell-derived extracellular vesicles as promising therapeutic agents in the treatment of diseases


Posted: 2022-01-04 20:00:00
Dental stem cells (DSCs), an important source of mesenchymal stem cells (MSCs), can be easily obtained by minimally invasive procedures and have been used for the treatment of various diseases. Classic paradigm attributed the mechanism of their therapeutic action to direct cell differentiation after targeted migration, while contemporary insights into indirect paracrine effect opened new avenues for the mystery of their actual low engraftment and differentiation ability in vivo. As critical paracrine effectors, DSC-derived extracellular vesicles (DSC-EVs) are being increasingly linked to the positive effects of DSCs by an evolving body of in vivo studies. Carrying bioactive contents and presenting therapeutic potential in certain diseases, DSC-EVs have been introduced as promising treatments. Here, we systematically review the latest in vivo evidence that supports the therapeutic effects of DSC-EVs with mechanistic studies. In addition, current challenges and future directions for the clinical translation of DSC-EVs are also highlighted to call for more attentions to the (I) distinguishing features of DSC-EVs compared with other types of MSC-EVs, (II) heterogeneity among different subtypes of DSC-derived EVs, (III) action modes of DSC-EVs, (IV) standardization for eligible DSC-EVs and (V) safety guarantee for the clinical application of DSC-EVs. The present review would provide valuable insights into the emerging opportunities of DSC-EVs in future clinical applications.

心筋の強化や他の疾患を治療する幹細胞療法は、ヒト臨床試験で有望視され始めている。 しかし、臨床成果の観察以外に、標的臓器内の移植細胞の有効性を評価するうえで再現性の欠如や使用期限、非侵襲的なツールの欠如は、幹細胞分野の進歩を遅らせてきた。 メリーランド大学医学部(UMSOM)、ペンシルバニア大学、およびエモリー大学の研究者らは、移植された幹細胞の有効性を追跡するのに血液検査が使用できると理論づけた。 彼らは、移植幹細胞からレシピエントの血液に分泌される エクソソーム と呼ばれる微小な細胞成分を分析した。…
