But current cloning research is heading the other way. It wants to clone cells from a human, so that we can grow various organs and body parts for transplant. The aim of this research, at least over the next ten years, is to clone any organs or body parts that you might need, from your own adult cells. They would take a cell from the inside of your mouth, take out the nucleus or DNA which is your own personal blueprint, and somehow use that as a trigger to grow more organs. The trick lies in that somehow.
Nobody wants to work with embryo cells in the long-term.
They are too hard to get hold of, too fragile, and fraught with ethical problems. But in the short-term, the scientists have to work with the embryo cells to learn how to make the DNA from adult cells produce any organ we want. But let's look further ahead. Well, it would be pretty easy to clone another you without your knowing about it. There are lots of body tissue samples around.
