عنوان انگلیسی The effects of adipose tissue-derived stem cells seeded onto the curcumin-loaded collagen scaffold in healing of experimentally induced oral mucosal ulcers in rat
چکیده انگلیسی مقاله Objective(s): Various therapeutic approaches, including stem-cell-based strategies and tissue engineering, have been proposed for oral ulcerative lesions. We investigated the effects of adipose tissue-derived stem cells (ADSCs) seeded onto the curcumin-loaded collagen scaffold in the mucosal healing of oral ulcers in rats.Materials and Methods: The current experimental study was conducted on 40 male Sprague-Dawley rats. Oral ulcers were created over both sides of buccal mucosa, and the rats were randomly divided into four equal groups: 1) an untreated group (negative control); 2) Teriadent-treated group (positive control); 3) group treated with curcumin-loaded collagen scaffold; and 4) group received the ADSCs (3 × 106 cells) seeded onto the curcumin-loaded collagen scaffold. Rats were sacrificed on 3rd and 7th day after ulceration for histopathological examination as well as measurement of tissue levels of myeloperoxidase (MPO), superoxide dismutase (SOD), and Interleukin-1 beta (IL-1β) activity. Results: Compared with the negative control, the tissue levels of MPO and IL-1β were significantly decreased in all treated groups (p < 0.0001); however, the SOD activity was elevated (p < 0.0001). The highest SOD activity as well as the lowest MPO and IL-1β levels were observed in the ADSCs-curcumin-loaded collagen scaffold group. The ulcer healing process at 3rd and 7th day follow-up was much more progressed in the ADSCs-curcumin-loaded collagen scaffold group in comparison with the untreated group (P=0.037 and P=0.004, respectively).Conclusion: According to the findings of this study, ADSCs seeded onto the curcumin-loaded collagen scaffold seems to have a promising potential for oral ulcer healing applications.
