Artificial: Scientists enter the animal testing stage

The kidney has grown up in the laboratory and has been transplanted into animals. It begins to produce urine, American scientists say. Similar techniques have been used to perform patients with simple body parts, but one of the most complex organs ever made.
A study shows that in the Journal of Natural Medicine, it is shown that artificiality is less effective than natural. But regenerative medicine researchers said there is a huge commitment in this area. Filter the blood to remove waste and excess moisture. They are also the organs with the greatest demand for transplantation and a long waiting list. The researchers’ vision was to take the old, and deprive all their old cells off the honeycomb-like scaffold. Cells are taken from the patient and will be reconstructed. This will have two major advantages over current organ transplantation.
The organization will match the patient, so they no longer need a lifetime to suppress the immune system to prevent rejection. This also greatly increases the number of organs available for transplantation. Most organs provided are rejected, however, they can be used as new templates. Researchers at the Massachusetts General Hospital have created the first artificial steps available. They spent the rats and washed their old cells with detergent. The rest of the protein network, or scaffold, looks just like a blood vessel and the drain includes a complex network.
Grow your own organs may look like an illusion, but there are also people who walk today and use this method to make organs. When it appeared in 2006, a major breakthrough was made in the water bladder made from the patient's own cells. Planted trachea was also transplanted. There are four levels of complexity in regenerative medicine: such as the planar structure of the skin, such as blood vessels, hollow organs (such as the bladder), solid organs such as kidneys, heart, and tubes. The last group is the most difficult because they are complex organs that contain many types of tissues.
The rat heart beats, and the lungs that have been cumulatively produced and grown have been able to keep the rats alive if it is only for a short time. The growth of solid organs is still in its infancy, but the study of these animals provides an interesting window, which may be the future of organ transplantation.
However, Dr. Harald Ott, chief researcher, said that restoring a small part of normal function may be sufficient: "If you are hemodialysis, then 10% to 15% of the kidney function has already made you independent of hemodialysis We must do our best. "The potential he said is enormous: "If you think about it in the United States alone, there are 100,000 patients and are currently waiting for a kidney transplant, and only about 18,000 transplants have been done for a year. I think that potential The impact of successful clinical treatment will be enormous."
The technology needs to be more effective so that a greater degree of renal function recovery can be achieved. Researchers also need to prove that they will continue to function for a long time. There will also be a huge human challenge. It is difficult to have cells in a larger organ in the right place.
