[Development of non-cellular dermis: a step towards a total artificial skin].

In large cutaneous defects due to severe burns, dermal mesenchyme healing has to be controlled in order to avoid granulation tissue that rapidly leads to important contractures and hypertrophic scars. We report a study about the use of an artificial dermis made of human collagen (I and III) and several glycosaminoglycans. This artificial dermis was grafted on Sprague-Dawley rats after a 9 cm2 skin excision on the back.
