The grafts were applied with the basal layer directed to the Vol. exposure the thickness of the keratinocyte sheet tran- siently increased then decreased to two cell layers at 2 weeks. Enzymatic treatment is typically used in the collection of epithelial keratinocyte sheets but it tends to break the adhesion basement membrane proteins.

However when sheets of cultured keratinocytes were applied to the treated dermis , cultured plastic for several days, the keratinocytes attached regenerated a new basement membrane. Introduction In 1975 Green devised a way of culturing human keratinocytes, Rheinwald which allowed them to form partially stratifying sheets on plastic. Cultured allogenic keratinocyte sheets are effective for diabetic foot wounds higher burns, , second- degree no reports of rejection have appeared. Reimers Kerstin Department of Plastic Reconstr uctive Surgery, Hand , Medical School Hannover Germany 1. All wounds in group II were identically dressed: Vaseline gauze supporting the cultured keratinocyte sheets was secured on the plastic wound with 8- O silk sutures, covered with a layer of sterile paraffin to protect.Cytokeratin 5 was localized in plastic the lowest cell layer in the epithelial sheet but cytokeratin 1 loricrin were localized in the. The development of new techniques modifications to overcome some of the disadvantages in cultured keratinocyte grafting has been motivated by several well- known drawbacks in the use of cultured epithelial autografts such as long culture periods, , lack of adherence, difficulty in handling, lack of dermal substrates high costs. However, there are some issues related to this treatment that still remain unsolved. Division of Plastic Surgery Surgery Department, Federal University of São Paulo – UNIFESP/ EPM .

Department of Plastic and Reconstructive Surgery. Burn treatment units that have this therapeutic tool started to use these cultured epithelial sheets in the treatment of the burn patient. tion possible by industrial laboratories and the clinical use of simple cultured keratinocyte sheets in plastic burn patients. The two- cell- layer structure is similar to that of the adult mouse epidermis.
Despite plastic these advantages allogenic keratinocyte sheets do not absorb exudates are still relatively expensive.
