Researchers from Hokkaido University have created the world's first artificial blood vessels using collagen derived from skin of salmon. In fact - scientists have successfully tested their blood vessels, replacing the aorta of rats: in two weeks has shown no problems. This exotic material, like the skin of salmon, has been chosen not casually: on only one island of Hokkaido in the processing of seafood is on the emission of about 2 thousand tons of salmon skin every year, and find it a useful application of the Japanese have still not succeeded.
Now scientists say that these two can produce thousands of tons of 600 tons of collagen a year for the manufacture of vessels. Another advantage of the fish skin is that science is not aware of any virus that is transmissible from the salmon people. Thus, the use of the collagen can be considered as safe, compared with collagen obtained from the cows and pigs. Recent risk of transmission of infectious diseases, such as mad cow disease.
However, with collagen from skin of salmon has not been without problems, because he "feared" the high temperatures - tayal at 19 degrees Celsius. Because of this, it can not be applied in the human body. However, scientists managed to refine the process of formation of collagen fibers and increase the melting point of up to 55 degrees Celsius. For the rats were established blood vessels with an internal diameter of 1.6 mm and a wall thickness of 0.6 mm. During testing artificial blood vessels practically nothing less present. At the turn - to check on animal collagen pokrupnee, such as dogs.
