Cloning

NOW THAT A DOG HAS BEEN CLONED,
can human cloning be far behind? How is cloning important to future therapeutic medical advances, such as safe transplant organs? Take a look at some our past articles and see how TIME explains the scientific and ethical aspects of cloning.

And while Congress usually gets the message on presidential vetoes -- no means no -- a nearly identical embryonic stem cell bill that has passed the Senate sailed through the House Thursday, setting up yet another opportunity for the President to veto a measure that is increasingly popular both with the public and its elected representatives.

A decade later, scientists are starting to come to grips with just how different Dolly was. Dozens of animals have been cloned since that first little lamb -- mice, cats, cows, pigs, horses and, most recently, a dog -- and it's becoming increasingly clear that they are all, in one way or another, defective.

But it's hard to find any scientist today who believes him. Even if Hwang's two remaining triumphs, Snuppy and the first human cloning, emerge untainted, urgent questions remain. How did his now invalidated stem-cell paper get into a major scientific journal? How did such serious flaws go undetected for months? And could he have knowingly taken such foolish risks?

It also raised two big questions. The first, from many a dog owner: When can I clone my dog? The second: What are they going to clone next? The answer to the first is not very soon. The Korean achievement proves that cloning a dog is possible, not that it's easy.

This is the sixth-floor lab in Building No. 85 at Seoul National University, the center of operations for Woo Suk Hwang, the South Korean scientist who made headlines last week when he announced that his team, using Dolly-the-sheep techniques, had created 11 human stem-cell lines perfectly matched to the DNA of human patients--a giant leap beyond anything any other lab has achieved.

California and New Jersey have passed laws specifically authorizing the cloning of human eggs to create stem cells (so-called therapeutic cloning), and the legislatures of seven other states, including Illinois and New York, are considering similar bills.

What makes the achievement even more significant is that it gives doctors a way to create stem cells bearing a patient's own DNA. Tissues grown from those cells could replace diseased tissue in the patient without any risk of
rejection.

There is a near consensus for outlawing what the Raelians claim to be doing—cloning one person's cells in order to grow a genetic replica—on the grounds that the risks are too great and the moral costs too high.

Cc is the name the scientists behind the first cloned house pet gave their creation, a shorthaired calico that is a genetic (though not a visual) duplicate of her biological mom.

The challenge facing cloning pioneers is to make the case convincingly that the technology itself is not immoral, however immorally it could be used.

The sugar-free piglet that was eventually born could then be cloned over and over as a source of safe transplant organs.

Because the copy would often be born in a different family, cloned twins would be less alike in personality than natural identical twins.

The cloned mice were perfectly normal in all respects. They could mate and give birth, and their DNA was so robust that they themselves could be cloned—and their clones
cloned.

Spurred by the fear that maverick physicist Richard Seed, or someone like him, will open a cloning clinic, lawmakers are rushing to enact broad restrictions against human
cloning.

Dolly is living proof that an adult cell can revert to embryonic stage and produce a full new being. This was not supposed to happen.

The disadvantage of embryonic cloning is that you don't know what you are getting. With adult-cell cloning, you can wait to see how well an individual turns out before deciding whether to clone it.

A line had been crossed. A taboo broken. A Brave New World of cookie-cutter humans, baked and bred to order, seemed, if not just around the corner, then just over the horizon.
