A group of U.S. biotechnologists at Rice University in Houston, Texas is managed, a potentially crucial step in the production of artificial organs. They created using a new 3-D-printing-process-soft blood vessels and air passages, such as in a lung, and were able to show that the so-called Hydrogel-made structures are able to, blood with oxygen enrichment.
What’s a focus stack, you ask? Well you take a series of photos, like so, and then use software like ZereneStacker or Helicon. They let you align all the photos and then select the most in-focus pixels from each image to make the composite. pic.twitter.com/FgIwRBLGgL

An important role in the new approach, the group presented to the researcher Jordan Miller in the journal Science, artificial colour tartrazine (E 102). This substance is important for the 3-D-printing-process – for the people, as the investigations will show. This could be the method the determining factor in the use of 3-D, as previously used substances as carcinogenic, mutagenic known.
E102 method also works with live cells
Miller and his Team tried to a kind of artificial lung replica and wanted to test if oxygen from a lungs bag-like Air into the blood system can occur. For this purpose, you were oxygen-poor red blood cells in the blood vessel system around the air bag. And in fact, were saturated at the Exit of the vascular system, the blood cells with oxygen. As a replacement for breathing air, the researchers used pure oxygen, in the air bag pumped.
The researchers also showed that their method can in principle also be used in combination with living cells in the body. They made artificial fabric and mounted on genuine liver cells. Then they implanted it in mice and could show that the cells survived the implantation.
The solution for all the problems in transplantation?
artificially produced, printed organs promise a lot of Doctors, patients and companies in the medical industry. Proponents suggest that you can solve two problems of transplantation medicine: there are far too few donor organs. On the other hand, the patients need to take even after successful Transplantation is often life-long medication to prevent a rejection reaction of the body. In the case of bioengineered organs, however, can be cells of the body of the patient. The body’s own cells are not rejected in the rule.
the end of a organ donation organ donation
before someone comes up as a donor question, you need to find two experienced Physicians independently the brain death. This occurs as soon as in the cerebrum, cerebellum and brain stem no more activity can be measured. Thus, the organs are not damaged, it must be ventilated to the donor or the donor’s artificial.
If it is clarified, that organs should be removed, it is examined the brain-dead donor on tumor diseases and infections. This is to ensure that the receiver of an organ is not compromised.
The data of the donor to the European exchange Euro to be sent plans of the TRANS. Here is wanted on the waiting lists for suitable recipients. The waiting lists to ensure that those who get the body that need it most. It is regardless whether a Person is rich or poor, famous or unknown to the Public. After the scandals of 2011, the controls were tightened.
are Then taken from the deceased, the organs that he was willing to donate. The corpse is then prepared for viewing and can be buried. The organs are cooled and Packed and get to their destination. You will be transported by ambulance or, in urgent cases, by plane. In the Germany-wide well 50 transplant centers to be transplanted.
The trade in organs, according to the law is prohibited and is punishable by up to five years in prison. Watered-down penalties for the sale and purchase of products manufactured from tissues and organs.
