More Tissue Engineered Skin
From the Sydney Morning Herald: "A full thickness artificial skin which should dramatically reduce the pain and scarring associated with skin grafts is being developed by Sydney researchers. Burns experts from the University of Sydney and Concord Hospital have started animal trials of a living skin that is grown outside the body and is completely functional when grafted on to the body. Unlike traditional skin grafts, which involve only the thin outer layer of the skin known as the epidermis, the new skin will be able to replace the crucial second layer of skin called the dermis. ... It takes the body weeks to grow into a skin graft and in that time a lot of excess elastic fibres and collagen will be produced that will then turn into a scar. The scar contracts and it can get so tight that patients lose the movement of their mouth and can't talk, or they can't bend their fingers. ... Initial testing of the artificial dermis in mice has found it does not scar and contract when it is transplanted. ... The research has been so successful that a new foundation has been created to centralise the burns research being done at three Sydney hospitals. ... They hope to create scaffolds that can individualise the skin, allowing it to be different colours."
