Abstract

Background: This study was designed for the evaluation of Acellular Dermal Matrix (ADM) as a scaffold for adipose-derived stem cell transferring in the rat model.

Methods: This experimental study was done in the Burn Research Center of Iran University of Medical Sciences and Bonyakhteh Research Center, Tehran, Iran according to the standards of laboratory animals. Overall, 26 healthy Sprague-Dawley rats were used. Two of them were used to prepare ADM. In group one, the first wound on each, rat was spread with the mixture of fibrin gel and autologous stem cell. Only the stem cells combined with fibrinogen were spread on the other wound. In group two, the first wound on each rat was covered only with ADM, and the second wound was covered with gauze Vaseline. To perform sampling we used observation and photography at 7-30 days. Overall, 48 samples were taken of all the rats using skin punch biopsy on the 30th day for histopathology evaluation.

Results: There were significant differences in each group; however, the difference between different groups on days was not significant. In pathology, epithelialization, vascularization, the amount of collagen, collagen arrangement, the number of fibroblasts, and inflammation indices were investigated. The total score in each group was used for analysis. In statistical analysis, there was no pathology score difference among groups.

Conclusion: Using stem cells with or without ADM could not enhance the process of wound healing or improve pathology indices.
