In this article, scientists took the next step forward in genetics. Malcolm Ritter wrote about how human cells have been placed inside the embryos of pigs. These types of animals with cells from different species are called chimeras. The injected human stem cells in the pigs are projected to be the first step towards growing livers, hearts, pancreases, and other human organs. The researchers believe this will ease the shortage of human donors for transplants. As the pigs grow the human organs will grow in place of their own. Once the organs are ready to be removed, the pigs will be euthanized. Even though such mixing has been done on rats and mice before, this type of human-animal research has raised ethical concerns in the science world.
My older brother came to me with this article in the Atlantic City Press. This type of information sounds so futuristic and bizarre to me. I have heard of people using pig valves for heart repairs, but never would I think of using pigs to harvest human organs. This is an amazing revolution for doctors and transplant patients. This will most definitely be up for ethical discussions among certain individuals, but I believe this will save the lives of many.
