Researchers at Hokkaido University in Japan have made a breakthrough in the development of artificial blood vessels by using collagen extracted from squid skin. The goal of this study is to create artificial vessels that could one day be used to treat heart conditions such as myocardial infarction.
Through advanced techniques, the scientists modified the structure of the collagen found in squid skin, significantly increasing its heat resistance to 55 degrees Celsius. This improvement allowed them to produce an artificial blood vessel with an inner diameter of 1.6 mm and a wall thickness of 0.6 mm. In late February, they successfully transplanted this vessel into the abdominal aorta of a rat.
The results were promising: the artificial vessel expanded and contracted in sync with the rat’s heartbeat, demonstrating comparable strength and elasticity to a natural aorta. This marks a significant step forward in the field of bioengineering and tissue regeneration.
In related news, researchers at Kyushu University in Japan have also developed a double-layered artificial blood vessel using polyurethane. This design is known for being soft, flexible, and highly effective, offering improved performance over traditional models.
These advancements highlight the growing potential of biomaterials in medical applications, bringing us closer to more effective treatments for cardiovascular diseases. As research continues, we may soon see these innovations translated into real-world solutions for patients around the world.
