Through injecting human cells into a sheep's fetus, â€œscientists have created the world's first human-sheep chimera- which has the body of a sheep and half-human organs.â€ The sheep has approximately 15 percent human cells and 85 percent animal cells.
The sheep will ultimately be used for organ transplants.
Implications - Scientists plan to make the process suitable for human transplant by extracting stem cells from the donor's bone marrow and implanting them in the peritoneum of a sheep fetus. Then, once the lamb is born, its liver, heart, lungs and brain would have enough human characteristics to make them suitable for transplanting. Oh, what a brave new world that has such wonders in it!
