'In' artificial liver from sugar

Scientists have just taken a step closer to the technology of artificial liver development, after a team of researchers in the US created molds made of sugar to make blood vessels grow.

Scientists are still trying to create artificial blood vessels.

Scientists have long experimented with 3D printing technology to create cells and blood vessels, creating a layer-by-layer cell structure from artificial cells.

But those synthetic synthetic cells often die before the cells actually form.

However, the technology of using 3D printers using sugar as a material could one day be used to create internal organs implanted into human bodies.

According to the article published in Nature Materials, TS. Jordan Miller and TS. Christopher Chen of Pennsylvania University, the biggest challenge to know how to develop artificial cells is to know how to keep these cells alive, because when combining many natural cells and artificial cells, the cell This will take the oxygen and nutrients of the neighboring cells, causing the neighboring cells to choke and die.

Scientists at the University of Pennsylvania and the Massachussetts Institute of Technology (MIT) decided to build an artificial blood vessel system similar to the cardiovascular system of the body by creating a framework for artificial blood vessel cells to reside. .

Dr. Miller said that the technique is similar to creating a wax-shaped flower vase, then surrounding it with molten metal, then heating it to remove the wax.

But instead of using wax, scientists use sugar.

Although researchers have not performed any actual transplant, they say they want to prove that they can create tissues and blood vessels on a frame, paving the way for the creation of a complete organ. Future.
