Organ donation
-
Researchers have announced success from a pair of experimental pig-to-human heart transplant procedures completed on recently deceased human subjects who were kept on mechanical ventilation for three days while the organs were monitored in their bodies.
-
Getting an organ from donor to recipient is a race against time, with many going to waste. Now, researchers in Australia have identified new cryoprotectants that could preserve organs and tissues for much longer without damaging them.
-
Matching blood types from donor to recipient is a major problem in organ donation. Researchers have now developed an enzyme treatment to convert donated organs to the universal O blood type, allowing them to be safely transplanted into any patient.
-
A major challenge when it comes to preserving tissues and organs for transplantation is preventing the buildup of ice crystals that can cause critical damage, but an emerging technology may help sidestep the whole issue.
-
Organ transplants save lives, but rejection is a serious issue. That risk can be reduced by stripping donor cells out of the donor organ and replacing them with the recipient’s own, and now scientists have made that process safer with a protein bath.
-
Imagine needing a liver transplant and, instead of waiting for a donor, a new one could just be grown from your own skin cells. In a big step towards this, mini human livers grown from stem cells have been successfully transplanted into rats.
-
In organ transplants, rejection by the recipient's immune system is a risk. Now researchers at Yale have discovered a molecule that plays a role in triggering a slow-acting type of rejection, which could be blocked to give patients a better outlook.
-
In what is being touted as a major breakthrough, scientists have developed a machine that can not only keep livers alive outside the body for a week, but can also rejuvenate damaged livers unfit for transplantation.
-
A new supercooling technique could greatly improve transplantation outcomes by taking the organs into the realm of subzero temperatures for the first time.
-
A new study, led by scientists from King’s College London, has discovered a new type of cell in the liver. The research describes the cell as having “stem cell-like properties,” with the potential to regenerate damaged liver cells and treat disease in the organ without the need for a transplant.
-
A disturbing portrait of forced organ harvesting from prisoners of conscience in China has been revealed in the final judgement of an independent panel established to investigate the issue. The report details evidence of an organized infrastructure harvesting organs from persecuted groups.
-
Transplanting any organ is a complicated process, but lungs are particularly vulnerable to damage. Now, researchers have developed a way to repair that damage, keeping the lungs of pigs alive outside the body for up to 36 hours and allowing them to bring the organ up to a transplantable quality.
