Donor card: Artificial organs would reduce demand, says Professor James Neuberger.
A breakthrough in the development of artificial kidneys by Edinburgh University scientists could significantly reduce the demand for donor organs, a transplant expert has said.
Researchers used stem cells to create tiny kidneys, equivalent in size to those of an unborn infant, which they hope will be able to grow to maturity when transplanted into an adult's body.
The kidneys were created in a laboratory using a combination of cells from amniotic fluid, which surrounds babies in the womb, and animal foetal cells.
It raises the prospect of medics being able to create artifical kidneys and other organs for transplant patients in future, if the patient's amniotic fluid has been collected while they were in the womb.
Details of the groundbreaking research are due to be outlined at the Edinburgh International Science Festival in April.
Professor James Neuberger, associate medical director of Organ Donation and Transplantation with NHS Blood and Transplant, said the development was important because the donor pool is shrinking while demand increases as the population gets older.
Writing in Scotland on Sunday, he said that while there would still be a need for donor organs, artificial kidneys would reduce demand as well as being safer and healthier.
He said: "This sort of approach may well, in time, provide an alternative to using deceased donors for transplantation. Using organs created from a patient's own stem cells is very appealing from a safety perspective.
"Transplanted organs are second-hand organs and carry the risk of transmitting infections and cancer. Although we try to reduce that risk to a minimum, we can't abolish it. When and if these new organs become available, they will be a safer option than using deceased donors.
"This approach will go a long way to help with the organ shortage when it becomes a cost-effective and effective option. There will always be a need for donated organs for some patients as making organs from patients' own stem cells will take time and some patients can't afford to wait."
Scientists believe it will take another ten years for the technology to advance to the stage where they are able to transplant laboratory-grown kidneys into live humans.
Researchers in the United States have already succeeded in transplanting foetal kidneys into animals and growing them to adult size.
As well as improving the quality of replacement organs, researchers say the procedure of freezing amniotic fluid cells and growing artificial kidneys would be much more cost effective than keeping patients on kidney dialysis.
