| Research Abstract |
Mesenchymal stem cell are fasciating soureces for regenerative medicine. In previous studies, the ability of the proliferation and differentiation was different. Therefore, we investigated that this time clarify the conection between the clinical symptoms and the differentiation potential. Syonovial fluid was obtained from 13 patients with temporomandibular disorder (TMD). We culutured the adherent cells of the 6 in 13 samples that had the detail clinical findings. The subjects were divided into 2 groups. The first group included high differentiation of osteoblast and chondrocyte. The second group included poor differentiation.
The clinic symptoms was measured using the pain score and the mouth-opening distance. The pain score was assessed using a visual analogue scale. There was a significant difference in the osteogenic and chondrogenic potential among the two groups. In the clinical findings, there was a significant correlation in the pain score among the two groups. However, no difference was observed the mouth-opening distance. These results were demonstrated that osteogenic and chondrogenic potential of synovium-derived cells were significantly different in TMD.
