Half Human - What could possibly go wrong?

UC Davis researchers are injecting human stem cells into pigs. The goal is to create farm animals with human organs. The question of the hour is what if they create a pig, (or sheep), with human consciousness?

According to Boise State Public Radio: "The first step involves using new gene-editing techniques to remove the gene that pig embryos need to make a pancreas.

Working under an elaborate microscope, Ross makes a small hole in the embryo's outer membrane with a laser. Next, he injects a molecule synthesized in the laboratory to home in on and delete the pancreas gene inside. (In separate experiments, he has done this to sheep embryos, too.)
After the embryos have had their DNA edited this way, Ross creates another hole in the membrane so he can inject human induced pluripotent stem cells, or iPS for short, into the pig embryos.
Like human embryonic stem cells, iPS cells can turn into any kind of cell or tissue in the body. The researchers' hope is that the human stem cells will take advantage of the void in the embryo to start forming a human pancreas.

Because iPS cells can be made from any adult's skin cells, any organs they form would match the patient who needs the transplant, vastly reducing the risk that the body would reject the new organ."
