Prellis Biologics has brought the science fiction dream of printing human organs for transplant a step forward by developing a fast, high-resolution 3D printing technique that can produce living tissue that includes viable blood-carrying capillaries.

Surgeons at Johns Hopkins University have carried out the first ever complete transplant of a penis and scrotum. The procedure is being hailed as a success, with the recipient now on the mend and the team optimistic that he will regain close to regular function of his genitalia.

For the first time, scientists have successfully grown functioning human kidney tissue in the lab that is able to produce urine. The kidney tissue, generated from human stem cells, was implanted under the skin of mice and went on to develop into working kidney cells.

Ordinarily, when a donated kidney is waiting to be transplanted, it's cooled on ice. Doctors from Toronto General Hospital have become the first in North America to try another technique, however. They've kept a kidney alive at body temperature, using an altered heart-lung machine.

When people receive an organ transplant, they have to take drugs that keep their body's immune system from rejecting the organ. Unfortunately, these drugs suppress the immune system as a whole. There could be hope, however, in the form of a drug that's currently being developed to treat diabetes.

After losing 80 percent of his skin to a devastating genetic disease, a seven-year-old boy underwent an experimental treatment replacing his epidermis with new skin grown in a lab from genetically modified stem cells. Two years on from the dramatic surgery the boy is alive, well, and back at school.

NASA is conducting experiments aboard the International Space Station (ISS) aimed at learning how the lungs repair themselves in zero gravity. The lung tissue investigation promises to not only keep astronauts healthy, could provide a new source of artificial transplant organs.

The latest landmark development in the field of animal to human organ transplantation comes from a team of scientists who successfully created genetically modified piglets free of 25 retroviruses that are generally present in pigs but thought to cause harm to humans.

A team from Yale has developed an entirely new way of reducing the rates of organ transplant rejection by “hiding” the donated organ using targeted nanoparticles. This new process could significantly improve the success of a broad variety of organ transplants in the future.

A team at the University of Chicago recently developed a process to deliver CRISPR-based gene therapy to mice via skin transplants. The technique was effective in treating diabetes, but potentially can be utilized for a wide variety of diseases.
