The tissue origin effect of extracellular vesicles on cartilage and bone regeneration
Abstract
Direct implantation of mesenchymal stem cells (MSCs) for cartilage and bone tissue engineering faces challenges, such as immune rejection and loss of cellular viability or functionality. As nanoscale natural particles, exosomes or small extracellular vesicles (EVs) of MSCs have potential to circumvent these problems. It is significant to investigate the impact of the tissue origin of MSCs on the therapeutic bioactivity of their corresponding EVs for cartilage and bone regeneration. Here, rat MSCs isolated from the adipose, bone marrow, and synovium are cultured to obtain their corresponding EVs (ADSC-EVs, BMSC-EVs, and SMSC-EVs, respectively). The ADSC-EVs stimulate the migration, proliferation, and chondrogenic and osteogenic differentiation of BMSCs in vitro as well as cartilage and bone regeneration in a mouse model more than the BMSC-EVs or SMSC-EVs. Proteomics analysis reveals that the tissue origin contributes to the distinct protein profiles among the three types of EVs, which induced cartilage and bone regenerative capacities by potential mechanisms of regulating signaling pathways including focal adhesion, ECM-receptor interaction, actin cytoskeleton, cAMP, and PI3K-Akt signaling pathways. Consequently, these findings provide insight that the adipose may be a superior candidate in EV-based nanomedicine for cartilage and bone regeneration. STATEMENT OF SIGNIFICANCE: Extracelluar vesicles (EVs) of mesenchymal stem cells (MSCs) have been considered as a promising approach in cartilage and bone tissue engineering. In this study, for the first time, we investigated the tissue origin effect of EVs on chondrogenesis and osteogenesis of MSCs in vitro and in vivo. The results demonstrated that EVs of adipose-derived MSCs showed the most efficiency. Meanwhile, protein proteomics revealed the potential mechanisms. We provide a novel evidence that the adipose is a superior reservoir in EV-based nanotechnologies and biomaterials for cartilage and bone regeneration.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
