A chimera is a single organism that consists of cells from two or more individuals — that is, it contains two sets of DNA, with the code to make two separate organisms, somewhere within it. In the case of the human-animal chimeras made in the new research, the embryos contained mostly animal cells, with a relatively small number of human cells. To create the embryos, researchers injected human stem cells into animal embryos at an early stage of development.

In experiments aimed at finding ways to grow new human organs inside animals, researchers recently succeeded in making embryos that contained both pig and human and pig cells.

These so-called human-pig chimeras (which contained only a small number of human cells) were allowed to develop for several weeks in female pigs before the pregnancies were terminated, according to a new study.

"The ultimate goal is to grow functional and transplantable tissue or organs, but we are far away from that"

Experiments using human-animal chimeras are controversial, but last summer, the U.S. government said it planned to lift a ban on the use of federal funding for such research.

Ethics and science don't mix. At some point, the notion of morality will hold back the progression of science.

Damn right it should be legal but as a means to improve human life. However, this type of technology is not likely to be available to the masses because it interferes with population control. Also the pharmaceutical interest will lose money. It would be great to keep replacing organs but if you have brain damage then you are screwed anyway.

Antibiotics are available to the masses, even though they interfere with population control. So are surgeries, blood transfusions, vaccines, ambulances, clean water, IV fluids, skin grafts, vitamin supplements, colonoscopies, MRI imaging, fertility treatments, and seat belts. And a billion other things designed to keep people alive and healthy.
