Through injecting human cells into a sheep’s fetus, “scientists have created the world’s first human-sheep chimera- which has the body of a sheep and half-human organs.” The sheep has approximately 15 percent human cells and 85 percent animal cells.
The sheep will ultimately be used for organ transplants.
The process would involve extracting stem cells from the donor's bone marrow and injecting them into the peritoneum of a sheep's foetus. When the lamb is born, two months later, it would have a liver, heart, lungs and brain that are partly human and available for transplant.
