A natural agent that maintains mesenchymal stem cell (MSCs) viability, promotes osteogenic differentiation while modulating the immunological response could achieve success in regeneration during healing and may also prevent bone resorption and improve regeneration. We aimed to demonstrate that a Thymbra spicata var. intricata extract could induce proliferation, differentiation, and modulate the immune responses of mesenchymal stem cells (MSCs). Using xCELLigence, a real-time monitoring system, we obtained a growth curve of MSCs. A dose of 10 mu g/mL was the most efficient concentration for vitality. Osteogenic differentiation and antiinflammatory activities were determined by using an ELISA Kit to detect early and late markers of differentiation. The Osteonectin (ON, early osteogenic marker) level decreased while the Osteocalcin (OCN, late osteogenic marker) level increased in the T. spicata var. intricata treated group, suggesting that T. spicata var. intricata may accelerate osteogenic differentiation. Reduced level of the IL-6 cytokine in repsonse to TNF-alpha was evident. T. spicata var. intricata could be a promising osteogenic inducer in dentistry and could be used safely in biocomposites or scaffold fabrications.
