ABSTRACT
<p><b>OBJECTIVE</b>To establish a rat model of full-thickness skin defect to receive bone marrow mesenchymal stem cell transplantation for wound repair.</p><p><b>METHODS</b>A full-thickness skin defect measuring 4 cmx4 cm in 36 F344 rats, which were divided into 3 groups with the wound covered with alloskin graft, acellular dermal matrix, or petrolatum gauze. In vitro cultured BMSCs in the 5th passage were transplanted into the skin defect, and the time of wound dressing dissociation and number of transplanted Brdu-positive cells in the wound were observed 14 days later.</p><p><b>RESULTS</b>The alloskin graft resulted in significantly longer time before dressing dissociation, with greater number of Brdu-positive cells in the wound than the other two wound dressings (P<0.001). The acellular dermal matrix showed better effect than petrolatum gauze in terms of the dressing dissociation time and the viable transplanted cell number in the wound.</p><p><b>CONCLUSION</b>Alloskin graft can be ideal for covering the wound surface to protect the transplanted BMSCs in rats.</p>
