AIMS: Mesenchymal stem cells are an interesting source of material for regenerative medicine. The present study aimed at characterizing the phenotype and differentiation potential of adherent synovial fluid-derived cells from temporomandibular joint (TMJ) disorder patients.
MAIN METHODS: Synovial fluid collection takes place during TMJ cavity irrigation arthrocentesis under local anesthesia. The synovial fluid-derived adherent cells were fibroblast-like and spindle-shaped. Ex vivo-expanded synovial fluid-derived cells were shown to express STRO-1 and CD146, previously found to be present in bone marrow mesenchymal stem cells. Further, they were identified as being capable of differentiating into a variety of cell types including osteoblasts, chondrocytes, adipocytes, and neurons.
KEY FINDINGS: The present study demonstrates that human pluripotent cells can be isolated from synovial fluid. These synovial fluid-derived cells cannot only be derived from a very accessible resource, but are also capable of providing sufficient cells for potential clinical applications.
SIGNIFICANCE: These cells may play a role in the regenerative response during arthritic diseases and are promising candidates for developing novel cell-based therapeutic approaches for postnatal skeletal tissue repair.
