BACKGROUND: Osteoarthritis is characterized by chronic inflammation and progressive cartilage degeneration. Dental pulp stem cells may help regulate inflammatory responses and protect joint tissues.
METHODS: The authors evaluated clinical-grade human dental pulp stem cells in osteoarthritic macrophages and a rabbit model of osteoarthritis.
RESULTS: Dental pulp stem cells suppressed osteoarthritic macrophage activation and reduced cartilage damage in the rabbit model. The treatment also improved inflammatory conditions within the affected joint.
CONCLUSIONS: This study showed that dental pulp stem cells may help reduce inflammation and cartilage degeneration associated with osteoarthritis. These findings support continued investigation of DPSC-based therapies for joint repair.
