The present invention is a bioreactor wound dressing which includes a first layer, being a transport layer, in direct contact with a wound. It includes at least one layer of a permeable polymeric media containing, in equilibrium with body fluids, at least 40% by weight of liquid, and is impermeable for infectious agents of any kind and being permeable to water soluble substances having molecular weight up to at least 1000 Daltons. There is a second layer, being a fluid reservoir layer that is adjacent to the transport layer and is capable of containing between 40% and 100% of its volume of an aqueous liquid, wherein the transport layer and reservoir layer are permeably interconnected for aqueous solutions and are in a substantial osmotic equilibrium.
