Abstract

The rat skin was de-epithelialized using hypertonic saline solution and further decellularized with 1% sodium deoxycholate. The primary mouse embryonic fibroblast (P-MEF) cells were seeded on acellular dermal matrix (ADM). Fortyfive rats were randomly divided into 3 groups of 15 animals each. A 20×20mm2 full thickness skin defect was created on dorsum. The defect in group-I was dressed with standard dressing material, group-II with ADM, and group-III ADM seeded with P-MEF. In group-III, complete healing was observed at day21. The values of hydroxyproline contents in group III were significantly higher on days14 and 21 as compared to group-I. Significant decrease in glucosamine content was observed up to day28 in group-III. Native graft antigen challenged animals showed highest B-cell response. The acellular graft antigen challenged animals showed no B-cell response. Biopsy specimens showed minimum histopathological scores in group-III. The level of MDA and SOD increased significantly up to day14 in group-I. On day3, significantly lower values of GSH were observed in group-I whereas, significantly higher values of catalase were observed in all groups. SEM examination revealed well spread fibroblasts over the scaffold in group-III. These results indicate that bioengineered grafts can be used clinically to manage full thickness skin wounds.
