Soon scientific can frame tissues for transplantation which will not be torn away by an organism as tissues and organs of human or animal donors.

The transplantology develops not on days, and on hours. Professor John Fisher from university of Leeds (Great Britain), has declared at annual Conference of the British national network of studying stem cells the work with cellular skeletons, or substrates with which help it is possible to grow up tissues for transplantations. It and its colleagues framed biological skeletons from tissues of animals and people, - tissues of vessels, a meniscus and tendons which will not be torn away by immune system of the person. « If you take the sample of a living tissue and will take out all donor cells, you will have a substrate which consists basically of collagen. It is very convenient from the engineering point of view as it is plastic, strong and keeps all properties of a natural tissue, and also from the biological point of view, after all cells of the patient can be fixed with ease on it, and then be updated », - the professor tells. As own cells of the patient can"occupy"a donor substrate, the new tissue is accepted by its immune system"unconditionally". Thus the new graft possesses all properties necessary for successful transplantation.
Traditional techniques have a number of disadvantages. For example, blood vessels of pigs which replace to people, as a result of special procedure of adaptation become inert and lifeless. They cannot be updated and regenerate, and consequently in due course fail also them it is necessary to replace new.

«Our new biological substrates will provide surgeons with necessary tissues for treatment of blood vessels, knee cartilages and sports traumas, and also for replacement of the damaged ligaments, tendons and mitral valves», - scientists assure.
