Niesel and Norbert K HerzogArguably can say that the waiting list for organ transplants is the most unique.
This is an expensive \"do or die\" medical procedure with limited availability.
In the United States, the waiting time for the kidney transplant waiting list is from 5-
189 months, only 4 months less than 12 months.
Considering that someone is added to the organ waiting list every 10 minutes.
One day, one person died.
Remember, a donor can save up to eight lives by using multiple organs.
As of 2016, there were 121,527 people on the waiting list for organ transplants and in 2015, but only about 15,000 donors.
Despite advances in transplant technology and national efforts to stimulate organ donation, the difference between demand and supply remains significant.
The gap between supply and demand for transplanted organs has led to desperate measures to obtain organs.
In the Far East, there is a thriving black market for organs, where some people rob less fortunate people, or some report kidnapping or even murder to get them.
There are some options.
The researchers have developed a method of using animal organs for transplant, known as Alien transplants, to narrow the gap between transplanted organs.
Several countries, including Russia and New Zealand, have approved clinical trials for the treatment of type 1 diabetes using pig-derived cells.
However, different transplants are controversial.
A major concern is the fear that animal viruses will be introduced into humans.
Finally, it is important that there are a number of religious, social and ethical issues that will pose a challenge to a large-scale transplant of the same kind.
You may have heard about the impact of 3D printing, which some call the beginning of a new industrial revolution.
3D printing is an improvement in office inkjet technology, but the nozzle moves back and forth, up and down to deposit plastic or other molten material to form a 3D object.
In medicine, 3D printing is important for children\'s prosthetic limbs, and replacement parts can be produced as children grow.
The surgeon has been using this technique to make a working model of the reconstruction operation.
The orthopaedic doctor makes a working model of the fracture to optimize the placement of screws and steel plates before the operation, and the dentist\'s office makes crown and false teeth.
New advances in 3D printing are beginning to produce organizations that can be ported one day.
This bioprinting uses this technique to add a layer of biocompatible material to make scaffolding, and then to add tissue-specific cells to grow on it.
This scaffold provides the shape and structure of the tissue according to the anatomical location and needs.
For example, the bio-printed trachea will be printed to the exact size required.
In the end, biocompatible materials will degrade, leaving new tissues.
A new bioprinting technology also provides space for blood vessels to ensure that once implanted, the tissue will receive nutrients and oxygen from the blood.
The researchers used this technique to print cartilage in the shape of the human ear, muscle and jaw.
These engineered tissues remain alive after being implanted in mice and begin to develop blood supply.
While this is the first step, we can review these steps and characterize them as \"proof of principle\" for printing organs for human transplant \".
Ultimately, this will mean saving lives and creating an infinite supply of life-saving organs for the transplant.
