Abstract :

Background and Aim: Stem cells are cells that can proliferate to form a new tissue, leading to its use in regenerative therapy. Stem cells will secrete biological factors, such as growth factors, cytokines, and other proteins to their surroundings and culture medium/conditioned medium (CM), altering tissue physiology. These factors can help wound healing, but their effect on third-degree burns is poorly understood. This research aimed to study the activity of mesenchymal stem cell-conditioned medium gel in healing and repairing third-degree burns on rats skin. Materials and Methods: Twenty-four Sprague-Dawley rats with burn wounds on the dorsal area were divided into four groups; the first group was treated with Cm gel, with a concentration equivalent to 0.05% protein, the second group was treated with a placebo gel, the third group with silver sulfadiazine (SSD) cream (SSD-Burnazin contain 10 mg/g SSD), and the fourth group was not given any treatment, for 21 days, and on the final day, the rats were sacrificed, and the skins were taken. All topical treatments completely cover the wound area. Results: Wound healing process indicators observed include wound diameter, scabs' formation, blister formation, and hair growth every day. The skins taken were processed with hematoxylin-eosin and Masson's trichrome staining. The indicators studied include neutrophil infiltration, mononuclear cell infiltration, neovascularization, collagen area, and re-epithelization ratio. Conclusion: CM shows better wound healing than other groups and faster hair growth. Keywords: conditioned medium, mesenchymal stem cell, third-degree burn.
