Abstract: Objective: To investigate the therapeutic effect of Ad-HGF-GFP of ADSCs combined with injectable hydrogel on the repair of damaged cartilage in the microenvironment of rabbit temporomandibular arthritis. Methods: ADSCs were isolated from rabbits and cultured in vitro. Cells were transfected with adenovirus-mediated HGF and injectable hydrogel were prepared. Then animals were randomly divided to five groups: group A (blank control); group B; group C (treated with ADSCs); group D (treated with ADSCs combined with injectable hydrogel); group E (treated with Ad-HGF-GFP-ADSCs combined with injectable hydrogel). All animals were sacrificed 3 or 9 weeks after surgery, and condylar cartilages were harvested and analyzed by scanning electron microscope, histomorphometric analysis, and real-time PCR. Statistical analysis was performed with SPSS 17.0 software and statistically significant differences were assessed by t-test. All statistical analysis was considered significant when P<0.05. Results: Electron microscope scanning and histomorphometric analysis indicated improvement of condylar cartilage in group D and E, compared to those in the group B and C. Real-time PCR showed that the

expression of mmp13 gene in group E and A was comparable but decreased in group C and D, the difference was statistically significant. In contrast, the expression of TIMP-1 gene in group E and A was comparable but increased in group C and D, and the difference was statistically significant. Conclusion: Adenovirus-mediated HGF transfection of ADSCs combined with injectable hydrogel could promote the repair of temporomandibular joint arthritic condylar cartilage in rabbits.
