The exosomal miRNAs in OA
Exosomes miRNAs | Exosomes source | Target gene | Biological effects | Reference |
---|---|---|---|---|
miR-92a-3p | BMSCs | WNT5A | Promote cell proliferation and increase matrix synthesis in OA primary chondrocytes. | 190 |
miR-26a-5p | BMSCs | PTGS2 | Promote the survival of synovial fibroblasts and reduce synovitis in Rat OA model. | 186 |
miR-135b | EMSCs | Sp1 | Enhance chondrocyte proliferation in vitro and promote cartilage repair in vivo. | 221 |
miR-100-5p | AMSCsSHEDs | mTOR |
