Country to Lift Ban on Growing Human Organs in Animals

A Japanese government-commissioned expert panel has greenlighted controversial scientific experiments to grow human organs inside the bodies of animals as early as this fall.

Under the auspices of the Education, Culture, Sports, Science and Technology Ministry, the panel produced a report on research involving the development of human organs in the bodies of pigs and other animals. In the report, the panel concluded it would allow researchers to implant an animal embryo (a fertilized egg) containing human cells into an animal’s womb and have the animal give birth.

One method being considered for growing human organs inside animal bodies involves injecting human induced pluripotent stem (iPS) cells into an animal embryo and then returning the embryo to an animal’s womb to be birthed. The embryos are genetically modified to prevent specific organs from being created. . . .

The panel concluded such research could lead to discovering the underlying causes of diseases, securing organs to be used for transplants, and developing new treatments. Such research is already permitted in the U.S. and the U.K.

However, the panel in the same report decided not to allow research that could produce a creature ambiguous enough to blur the line between humans and other animals, crossbreeding of animals born as a result of the method, and fertilization using human germ cells.

Major Nation to Drop Ban on Organ Harvesting

The government of Japan is revising guidelines on the creation of chimeric human-animal embryos to permit organ harvesting and other experiments.

The Ministry of Education, Culture, Sports, Science and Technology is expected to drop a current ban on the procedures, which involve creating embryos including both human and animal cells and injecting them into the uteruses of pigs and other lab animals.

Currently, Japan permits only the injection of cells, such as human induced pluripotent stem cells (iPS cells), into fertilized animal eggs. A panel of experts approved the transplantation of the resulting embryos into the uteruses of animals and the resulting offspring. Animals such as pigs are being considered for the procedure because the sizes of their organs are close to those of humans.

Creating human organs in animals, they say, could help address the shortage of organs for transplants. Also, it is hoped that creating animals that can develop human diseases could aid research into the development of new medical treatments for humans.

The panel also approved research to produce human brain cells, eggs and sperm, but it maintained a ban on the creation of animals with high cognitive abilities similar to humans. (Read more from “Major Nation to Drop Ban on Organ Harvesting” HERE)
