The Role of Extracellular Vesicles Derived from MicroRNA-146a-modified Mesenchymal Stem Cells in Modulating Inflammation in Experimental Glenohumeral Osteoarthritis.

Glenohumeral osteoarthritis (GOA) is characterized by chronic inflammation leading to joint damage. Extracellular vesicles (EVs) derived from mesenchymal stem cells (MSCs) are promising therapies because of their immunomodulatory functions. The anti-inflammatory effects of EVs from human Adipose-derived MSCs (hADSCs) overexpressing microRNA (miR)-146a were investigated in experimental GOA in this study.

Micro-223 Promotes Diabetic Osteoarthritis Progression by Regulating Cartilage Degeneration and Subchondral Bone Remodeling.

Objective: Our study was performed to investigate whether micro-223 promotes diabetic Osteoarthritis (OA) progression by regulating cartilage degeneration and subchondral bone remodeling.

Methods: The expression of miR-223 in human normal cartilage, OA cartilage, and subchondral bone tissue with or without DM was detected by real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR). miR-223 mimic or inhibitor was transfected into chondrocytes.
