Abstract (original English)
To investigate the feasibility of repairing damaged cartilage of rabbit condylar with TGF-β3-transfected adipose stem cells combined with OGP (osteogenesis peptide)-HA (hyaluronic acid)-ChS (chondroitin sulfate) scaffold. Rabbit ADSCs were isolated and cultured. The expression vector carrying TGF-β3 gene was constructed using recombinant adenovirus and transfected into rabbit ADSCs. The fluorescence expression of the cells was observed after 14 days and the efficiency of virus transfection was calculated. Western blot was used to detect the expression of TGF-β3 protein. Fifty rabbits were randomly divided into 5 groups: group A as blank group, group B as TGF-β3 transfected ADSCs group, group C as OGP-HA-ChS scaffold group, group D as ADSCs complex OGP-HA-ChS group, E group was TGF-β3 transfected ADSCs with OGP-HA-ChS. After the rabbit temporomandibular joint osteoarthrosis model was established, the animals were transplanted according to the experimental design. The animals in each group were sacrificed after the 3rd and 9th weeks of transplantation. Scanning electron microscopy, histological observation and real-time fluorescent quantitative PCR were performed accordingly. SPSS17.0 software package was used for analysis of variance and t test. Scanning electron microscopy and histological observation showed that the repair of cartilage lesions in group D and E was better than
