American scientists figured out how to recreate the dead man's arms and legs

For the first time in the world, scientists were able to create an arm living in the laboratory. And when pairing it with a mouse, this "biological limb" quickly fills blood and can move.

America found a way to re-create hands and feet for dead people

The groundbreaking study of Massachusetts General Hospital in the United States could one day help people with healed hands and legs recover as originally. Dr. Daniel Weiss, a body regeneration expert at the University of Vermont Medical School (USA), praised this as a breakthrough "turning science fiction into reality".

Researcher Dr Harald Ott from the Department of Surgery at Massachusetts General Hospital said: "We are currently focusing on the forearms and hands. However, the techniques can be similarly applied. with arms, legs and other parts of the limbs ".

In the UK alone, 60,000 people have lost their hands or feet due to illness, accident or war that chose to install fake limbs or in some cases donated donors . However, although fake limb technology is making progress, these hand and prosthetic products have limited range of movement and look unnatural.

Hands, arms and even legs can be implanted, but these surgeries are very complicated and patients have to use countless strong immunosuppressants (weakening the immune system) to prevent Their bodies refuse the implant for life.

In contrast, biological hands or feet developed in the laboratory are thought to have a more natural appearance and movement. And since they are made from the patient's own cells, they will not need to take immunosuppressive drugs.

According to research reports, Dr. Ott, who previously created kidneys, liver, lungs and even a heart beating in the laboratory, collected the forearm part of a dead rat. After that, he used bleach to "clean " it, remove the cells and leave only his frame.

The next frame is placed in an incubator-type bottle, which injects healthy muscle and blood cells and nourishes it with oxygen and nutrients. In only 2 - 3 weeks, the blood and muscle glands have regenerated.

When the upper limb is attached to a living mouse, blood rushes to it.Experimental animals can even move new claws.

Dr. Ott has now created dozens of such limbs and is beginning to experiment with baboon arms . Still, he warns there are many challenges to overcome, such as regenerating the nerves for hands and feet, and it will take at least another decade for the biological limbs of new people to be ready. experiment.
