Although mesenchymal stem cells (MSCs) derived extracellular vesicles (EVs) are promising for promoting cartilage regeneration, their clinical application is limited by inconsistent therapeutic effects and insufficient targeting capabilities. Mechanical loading shows potential to optimize MSC-EVs for OA treatment, while the underlying mechanism is not clear. In this study, EVs derived from mechanical loading-primed MSCs (ML-EVs) demonstrate prominent efficacy in maintaining ECM homeostasis and relieving chondrocyte senescence, thereby mitigating OA. Subsequent miRNA sequencing reveals that ML-EVs exert their effects by delivering miR-27b-3p, which targets ROR1 mRNA in chondrocytes and suppresses downstream NF-κB pathways. By modulating the ROR1/NF-κB axis, miR-27b-3p effectively restrains ECM degradation and chondrocyte senescence. To optimize therapeutic efficacy of EVs, miR-27b-3p is overexpressed within EVs (miR<sup>OE</sup>-EVs), and a chondrocyte-targeted peptide (CTP) is conjugated to their surface, thereby constructing dual-engineered chondrocyte-targeted EVs (CTP/miR<sup>OE</sup>-EVs). CTP/miR<sup>OE</sup>-EVs exhibit excellent ability to specifically target cartilage and ameliorate OA pathology.

Single-cell sequencing analysis revealed key cellular subpopulations and signaling pathways during differentiation. Furthermore, overexpression of the Hes1 gene significantly promoted the differentiation of UCMSCs to tendon cells and showed its therapeutic effect in rotator cuff injury repair in an animal model.

We showed that <i>in vitro</i>, circulating fibrocytes (CFs) can (1) shear and stabilize the microvasculatures formed by vascular endothelial cells (VECs) in a collagen gel, (2) form gap junctions with VECs and (3) induce basement membrane formation. CFs transplanted into nude mice along with VECs in either collagen gel or Matrigel exhibited activities similar to those mentioned above, that is, sheathing microvasculatures formed by VECs, inducing basement membrane formation and facilitating the connection of the engineered microvasculatures with the host circulation. Interestingly, the behaviour of CFs also differs from that of human brain vascular pericytes (HBVPs) <i>in vitro</i>, which often infiltrate the lumen of capillary-like structures in a mosaic pattern, actively proliferate and exhibit lower endocytosis and migration capacities. We concluded that CFs are a suitable cellular source for mural cells in the construction of tissue-engineered microvasculatures.</p>","PeriodicalId":17384,"journal":{"name":"Journal of Tissue Engineering","volume":"16 ","pages":"20417314251315523"},"PeriodicalIF":6.7,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11775981/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143066082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
