Easily shortened blood organizations to damage damage to broken tissue

Small balls in the lab-grow blood The vessels helped restore blood flow to the injured tissue of rats, minimizing necrosis. This method can be a day available to reduce some damage caused by accidents or blood clots.

Researchers used to have previously clumps in the roots of the lab-buad, known as the organs, by immersing cells in a chemical chemical. But this method spent a few weeks and often made vessels that were poorly imitating the bodies, saying Juan Melero-Martin At Harvard University.

In an alternative approach, Melero-Martin and his colleagues of genetically engineered man Stem Cells made by reprogramming skin cells. They give stem cells into a genetic order that causes them to grow in blood vessels in the presence of antibiotic doxycycline. “We have done the bloodshons of blood in the blood of only five days,” Melero-Martin said. Ships also have protein and gene activity levels that are very similar to those found in the human body, he said.

To test if their organizations can regard the injured tissue, researchers cut the blood supply to a leg in many rats, so no less than 10 percent of the normal level. An hour ago, they set up 1000 organizations on each of the wound sites.

If the immagination of rats two weeks ago, the team found that the blood vessels include animals, which restores blood supply to 50 percent of normal levels – a large amount, say Oscar Abileek In Stanford University in California. “For example, in a state of heart attacks, if you can restore a large blood flow of tissue, at a reasonable time, that is important for reducing tissue damage.”

After treatment, about 75 percent of animals with a small degree of dead tissue, Melero-Martin said. Among those who have been injured and not given the housed blood vessels, most of the tissue of the leg died at about 90 percent of individuals.

In another experiment, researchers use organizations in treating rats with type 1 diabeteswhere pancreas damage causes blood sugar level to get high. They know that the implantation of organists in rats along with pancreatic tisstans prolonged their blood sugar control, compared with pancreatic tissue transfer only.

But further study of larger animals such as pigs are needed before the way people are tested, says Abilez. Melero-Martin said the team hopes to do this, which increases that human studies can be realistic to take place within five years.

In addition to taking damage to the tissue, those who know helps with mini-organs that are better to imitate the body or even miniators that scientists study scientists to study and treat the scientists.

“Until recent, organizations can only grow in a specified size, because they have no blood vessels – so, after a specified size, they began to die,” said Abilez. “This study offers a way to add blood vessels to organs to better represent a person’s physiology, and more useful for developing treatments.”
