wounds heal in a short time without scars. This technique is called SkinDot. Alternatives to skin grafting There are alternatives to skin grafting including skin substitutes using cells from patients, skin from other animals, such as pigs, known as Xenograft and medical devices that help to close large wounds. Xenograft was originally known as "zoografting." Other animals that can be used include dogs, rabbits, frogs, and cats, with the greatest success achieved with porcine skin. Other skin substitutes include Allograft, Biobrane, TransCyte, Integra, AlloDerm, Cultured epithelial autografts (CEA). There are medical devices that helps close large wounds. The device uses skin anchors that are attached to healthy skin, an adjustable tension controller then exerts a constant pulling tension on sutures looped around the skin anchors, the device gradually closes the wound over time.
