Abstract:
Objective:To analyze related factors on the number of mesenchymal stem cells in the synovial fluid of the temporomandibular joint (TMJ) and provide an research basis for understanding of the source and biological role of mesenchymal stem cells derived from synovial fluid in TMJ.
Methods:One hundred and twenty-two synovial fluid samples from 91 temporomandibular disorders (TMD) patients who visited in Department of TMJ Center, Guanghua School of Stomatology, Hospital of Stomatology, Sun Yat-sen University from March 2013 to December 2013 were collected in this study, and 6 TMJ synovial fluid samples from 6 normal volunteers who were studying in the North Campus of Sun Yat-sen University were also collected, so did their clinical information. Then the relation between the number of mesenchymal stem cells derived from synovial fluid and the health status of the joints, age of donor, disc perforation, condylar bony destruction, blood containing and visual analogue scale score of pain were investigated using Mann-Whitney U test and Spearman rank correlation test.
Results:The number of mesenchymal stem cells derived from synovial fluid had no significant relation with visual analogue scale score of pain (r=0.041, P=0.672), blood containing (P=0.063), condylar bony destruction (P= 0.371). Linear correlation between the number of mesenchymal stem cells derived from synovial fluid and age of donor was very week (r=0.186, P=0.043). The number of mesenchymal stem cells up-regulated when the joint was in a disease state (P=0.001). The disc perforation group had more mesenchymal stem cells in synovial fluid than without disc perforation group (P=0.042).
Conclusions:The number of mesenchymal stem cells derived from synovial fluid in TMJ has no correlation with peripheral blood circulation and condylar bony destruction, while has close relation with soft tissue structure damage of the joint.
