The standard treatment for extensive burn wounds is transplantation with meshed split skin graft. Disadvantages of this treatment are that healing of large full thickness burn wounds is still accompanied by scar formation. Even standard treatment, transplantation with a (meshed) split skin autograft, does not result in satisfactory functional and cosmetic appearance of the healed wound. Due to limited available donor sites meshes needs to be enlarged. Bigger enlargements of meshes give more scarring and mesh pattern are still visible in scars, probably because wound closure still needs several weeks. Application of cultured autologous keratinocytes may enhance wound closure and improve outcome of healing.
