The first artificial trachea made change

Swedish surgeons performed the world's first transplant of synthetic tracheal:

As reported by the BBC B , the artificial organ, scientists have built up material from stem cells of the patient. This technique is not required for transplant donor and specific drugs and the risk of tissue rejection is minimal.

The patient is a 36-year-old native of Africa who has been diagnosed with cancer of the airways. According to doctors, he is now on the mend. Artificial trachea produced a medical research institute in London.

On medicine in the future, scientists plan to use a similar technique for transplantation of artificial arteries, heart valves, and even leather.

In the United States developed a gel that stimulates the recovery of spinal cord

South Carolina developed an innovative hydrogel, stimulating growth and regeneration of the spinal cord and spinal.

Novelty can be many times accelerate natural regeneration of tissue at the wound site.

Gel, while the effect of which doctors have only tested on laboratory mice, consists of a synthetic base with the addition of natural sources, enabling the reproduction of stem cells spinal cord.

The developers of the gel indicated that after a series of clinical trials, it will inflict on the people who have suffered serious injury, which resulted in a badly damaged spine. Finance the development of DOD.

In addition to the spinal cord, the hydrogel has also proven to be effective in treating brain injuries and skull reconstruction. According to physicians, created a kind of gel is a budget solution more effective method, when a patient transplanted tissue donors or injections of stem cells for replacement of damaged area.

Latest treatment options are very expensive and available to physicians do not always have the donation of organs and tissues.

The use of hydrogel in the area of ​​the spinal cord in laboratory mice could prevent extensive damage to the central nervous system and stimulate the growth of the body's tissues. "Another important advantage of the gel is its liquid form.

Through which it can be administered by simple injection, similar to that carried out the procedure for taking a puncture. In addition, the gel can be mixed with other drugs, prescribed by your doctor "- the researchers say.

According to developers, in the case of using the hydrogel, the healing process of spine fracture did not last for more than eight weeks, and if added to the injection of undifferentiated stem cells, the healing took place even faster.
