Keratinocyte grafting: a new means of transplantation for full-thickness wounds.
Twenty adult individuals with chronic leg ulcers caused by venous insufficiency, and 5 patients with full-thickness burns were treated. Twenty of the patients (15 with leg ulcers and 5 with burns) were grafted with separated autologous keratinocytes. In these cases the cells were fixed to the wound bed by a fibrin net. Five other patients (with leg ulcers) were treated with fibrin without keratinocytes. In 16 of the 20 patients grafted with keratinocytes in a fibrin net, the defect healed completely in 14 to 21 days. On the other hand, the fibrin net without keratinocytes failed to significantly accelerate the process of reepithelialization. Our experience suggests that a rapid healing of full-thickness skin defects can be achieved through keratinocyte grafting.
