The model that creates vascular networks within a minute can produce printed liver, kidney and heart to live.
Scientists from Stanford University have created a breakthrough in creating artificial organs, developing a computing model that gives a minute to the design of blood vessels for 3D printing of any organ, Newscentist reports. This method will help to overcome one of the major obstacles to the transfer of artificial organs – the absence of a tissue nutrition system.
Only 10% of patients in the world receive the necessary organs for transplantation. The 3D printing of organs is considered a potential solution to the problem, but artificial fabrics without the vehicles dies quickly. To date, the creation of such networks has occupied days or weeks. The new approach proposed by the team led by Alison Marsden is based on a math law that describes the natural branching of blood vessels in the body.
Researchers have tested the model by creating a vascular network of 25 channels for an annular structure with a diameter of 1 cm, which is printed from kidney cells. The structure is printed using cold gelatin particles, and then heated to body temperature – 37 ° C, which allows to form hollow channels with a diameter of 1 mm. Through these, the fluid with oxygen and nutrition is constantly pumped by them, mimicking the blood flow.
One week later, in the structure with blood vessels, the number of living cells was 400 times more than the control version with no blood vessels, though both were submerged in the same nutritional medium. Marsden explained that cells have just survived the vessels, as it is still impossible to print smaller, thinner capillaries required for the nutrition of remote areas. The team is already working on solving this problem.
According to Hyuug Talbo from the University of Paris-Sakle, the study has “pushed the boundaries possible” and may allow the creation of vessels for full body size not a week, but for some time. In the future, such networks may increase or even replace donor authorities.
The next stage is the seal of a full -fledged vascular system in large organs. If everything is in accordance with the plan, the first trials of printed organs in pigs can occur within five years.
We remind you, earlier it was reported that scientists developed 3D printing technology inside the body using sound.
