Artificial blood vessels from salmon skin

Structural researchers at Hokkaido University, Japan have recently extracted collogen from salmon skin to create artificial blood vessels.

Structural researchers at Hokkaido University in Japan recently extracted the collogen from salmon skin to create an artificial blood vessel, and transplanted this type of blood vessel into the artery of white mice, extend the life of the mouse.

During the extraction process, the most difficult problem for researchers is that this type of collogen does not tolerate heat, if the temperature reaches 19 ^° C, it will melt.

The researchers had to change the texture of collogen, strengthen the combination of molecules and succeeded in bringing the heat resistance to 55 degrees C. Collogen after the structural change was made. Artificial blood vessels with a diameter of 1.6mm, a vascular wall of 0.6mm thick and have been implanted into the artery in the abdomen of a white mouse.

The experiment has confirmed that the transplanted blood vessels are stretching to the beat of the rat heart, this artificial blood vessel also has the ability and elasticity like natural arteries.

The team has planned to test the function of this artificial blood vessel on larger animals such as dogs ., and hopes to develop an artificial blood vessel used to treat fibrosis. Hard arteries in humans.

Currently, artificial parts often take collogen materials from cows or pigs, but so it is easy to encounter many risks from mad cow disease. If it is possible to create artificial blood vessels from collogen of marine animals, the safety will be higher.
