Given these properties, eMSC EVs may offer potential benefits for meniscal repair. The meniscus, being partly vascularized, relies on diffusivity for solute trafficking. This study focuses on EVs transport properties characterization within fibrocartilage that remains unknown. Specifically, EVs were isolated from Crude and CD146<jats:sup>+<\/jats:sup> eMSC populations. Green fluorescence\u2010labeled EVs transport properties were investigated in three structurally distinct layers (core, femoral, and tibial surfaces) of porcine meniscus. Diffusivity was measured via custom fluorescence recovery after photobleaching (FRAP) technique. Light spectrometry was used to determine EVs solubility. Both Crude and CD146<jats:sup>+<\/jats:sup> eMSC EVs exhibited high purity (&gt;90% CD63CD9 marker expression) and an average diffusivity of 10.924 (\u00b14.065) \u00b5m\u00b2\/s. Importantly, no significant difference was observed between Crude and CD146<jats:sup>+<\/jats:sup> eMSC EV diffusivity on the meniscal layer (<jats:italic>p<\/jats:italic>\u2009&gt;\u20090.05). The mean partitioning coefficient was 0.2118 (\u00b10.1321), with Crude EVs demonstrating significantly higher solubility than CD146<jats:sup>+<\/jats:sup> EVs (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). In conclusion, this study underscores the potential of both Crude and CD146<jats:sup>+<\/jats:sup> eMSC EVs to traverse all layers of the meniscus, supporting their capacity to enhance delivery of orthobiologics for cartilaginous tissue healing.<\/jats:p>","DOI":"10.1002\/jor.25993","type":"journal-article","created":{"date-parts":[[2024,10,13]],"date-time":"2024-10-13T12:59:52Z","timestamp":1728824392000},"page":"457-465","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Human mesenchymal stem\/stromal cell\u2010derived extracellular vesicle transport in meniscus fibrocartilage"],"prefix":"10.1002","volume":"43","author":[{"given":"Gabi","family":"Schwartz","sequence":"first","affiliation":[{"name":"Department of Biomedical Engineering University of Miami Coral Gables USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Samir","family":"Rana","sequence":"additional","affiliation":[{"name":"Department of Kinesiology and Sports Sciences University of Miami Coral Gables USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alicia R.","family":"Jackson","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering University of Miami Coral Gables USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Clarissa","family":"Le\u00f1ero","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, UHealth Sports Medicine Institute, Miller School of Medicine University of Miami Miami USA"},{"name":"Diabetes Research Institute &amp;
