Scientists clone human stem cells from patients

South Korean scientists who cloned the first human embryo to use for research said on Thursday they have used the same technology to create batches of embryonic stem cells from nine patients.

Their study fulfills one of the basic promises of using cloning technology in stem cell research -- that a piece of skin could be taken from a patient and used to grow the stem cells.

Researchers believe the cells could one day be trained to provide tailored tissue and organ transplants to cure juvenile diabetes, Parkinson's disease and even to repair severed spinal cords. Unlike so-called adult stem cells, embryonic stem cells have the potential from the beginning to form any cell or tissue in the body.

Woo Suk Hwang and colleagues at Seoul National University report their process is much more efficient than they hoped, and yielded 11 stem cell batches, called lines, from six adults and three children with spinal cord injuries, juvenile diabetes and a rare immune disorder.

"This study shows that embryonic stem cells can be derived using nuclear transfer from patients with illness ... regardless of sex or age," Hwang told reporters in a telephone briefing.

"I am amazed at how much they have accomplished in just a year and the amount, the quality and the rigorousness of their evidence," Dr. Gerald Schatten of the University of Pittsburgh, a stem cell expert who reviewed the study, said in a telephone interview.

While the patients whose cells were copied do not stand at this time to benefit, the researchers hope to study the cells to understand their conditions better.

They also say their method may be less controversial than other work with embryonic stem cells because, by their definition, a human embryo was never actually created.

The report, published in the journal Science, is certain to add to the growing U.S. political controversy over the federal funding of embryonic stem cell research.

Opponents say all such work is unethical and should be banned because human life begins at conception and should not be destroyed.

NO HUMAN EMBRYO

Hwang said his method differs from that first used to derive human embryonic stem cells in 1998 and he proposes using a new term for the cloned embryos -- a "nuclear transfer construct."

"I think this construct is not an embryo," he said. "There is no fertilization in our process. We use nuclear transfer technology. I can say this result is not an embryo but a nuclear transfer construct."

The sheep Dolly, the first adult mammal cloned, was made using nuclear transfer, in which the nucleus is removed from an egg cell, replaced with the nucleus of the animal or person to be cloned, and then fused. The egg begins dividing as if it had been fertilized and sometimes becomes an embryo.

Cattle, pigs, sheep, cats and other animals have been cloned using this method.

Schatten said when scientists first got stem cells from human embryos in 1998, they broke open the little days-old ball of cells called a blastocyst.

In the current study, he said, they simply laid down the blastocyst in a lab dish filled with human "feeder cells."

David Magnus and Mildred Cho of the Stanford University Center for Biomedical Ethics in California agreed.

"There is no reason ever to believe one of these things could ever become a human being," said Magnus, who with Cho wrote a commentary on the work.

"Even for people that believe that potentiality is the key to personhood, these things, whatever they are, they are not people. Somatic cell nuclear transfer is an ethically better way of producing stem cells than using excess IVF (in vitro fertilization or test-tube baby) embryos."

Schatten said the method could also eventually do away with the need for some animal experiments, which some people also find objectionable and which others say is not always a good way to predict human medical treatments.

Opponents of stem cell research had not had an opportunity to review the paper and could not immediately comment.

Having Fun With Intelligent Design!

By David Morris
Posted on May 23, 2005

I have just three words for biology teachers who are wringing their hands as school boards from Kansas to Pennsylvania force them to teach intelligent design as an alternative to evolution: Get over it.

Here's what I think. Science teachers can comply with the requirement and still offer their students a first-rate education. If done with imagination, the new curriculum could end up stimulating more learning and excitement than their traditional explication of Darwinian theory.

I wouldn't have made this argument 20 years ago. At that time, school boards' interventions were far more restrictive. Science teachers were obliged to inform their students that the story of Genesis was literally true. But in 1987, the U.S. Supreme Court put a stop to that by declaring the teaching of creationism in the classroom a violation of the Constitutional insistence on the separation of church and state.

The Court decision spawned a more nuanced and sophisticated approach by anti-evolutionists: intelligent design. Intelligent design is not creationism per se. It holds that higher forms of life are so complex they must have been created by an unspecified higher power. The key word here is "unspecified." Many school board members who support an intelligent design mandate believe that higher power is Jesus. But they aren't forcing anyone to teach that in schools.

What they do require is that teachers offer a critique of evolution and suggest alternative theories about the origins of life. How might a good science teacher comply with these new directives without compromising their principles or their dignity? Or to put it slightly more aggressively, how might a biology teacher educate his or her students while at the same time teach meddling school board members a lesson?

All teachers know that their first and hardest job is to gain the student's attention and interest. What subject best attracts a teenager's undivided attention? Sex. Happily, when it comes to evolution, sex is central.

I recommend that biology teachers begin by discussing Elisabeth A. Lloyd's decidedly scientific book, The Case of the Female Orgasm. No school board member should complain. The book's subtitle, "Bias in the Science of Evolution," clearly fits with the new requirement that teachers critique evolutionary theory.

Darwinians can explain the male orgasm. After all, the male ejaculation is necessary for the survival and perpetuation of the species, and if giving the male great pleasure while doing so promotes that, then natural selection would eventually endow the male orgasm with that characteristic.

When it comes to the human female orgasm, however, evolutionists are stumped. No other female of the animal kingdom experiences an orgasm. Professor Lloyd examines 21 evolution-based explanations for the female orgasm, and demolishes every one of them.

Here the biology teacher might offer the class the alternative explanation of intelligent design. Is the intelligent power simply leveling the playing field between the sexes? Or is Professor Lloyd right that the female orgasm is "just for fun," and the intelligent power is female?

Then there's the question of male homosexuality. From a Darwinian perspective, it's a puzzle. The theory of natural selection should guarantee the disappearance of males that don't reproduce. But they keep hanging around, in considerable numbers, in every culture and every era.

Evolutionists have their theories. Psychologist Louis A. Berman argues that it has to do with embryonic development. Medical doctor Lorne Warneke suggests that homosexuality actually offers a natural advantage. Homosexuals instill a more cooperative impulse that helps perpetuate the kinship group and tribe.

A good science teacher will follow the school board's guidance and propose intelligent design as an alternative explanation for male homosexuality. Could there be an intelligent power that has created and nurtured male homosexuality? Does that mean God is gay?

School boards require science teachers to offer alternative explanations about how life began. That presents still another opportunity for creative educators.

Evolutionists argue that life evolved over tens of millions of years via natural selection. Intelligent design advocates believe the creation of life was overseen and guided by an intelligent power.

The biology teacher should offer students creationism as a possible explanatory theory of the origins of life. And, of course, subject it to the same rigorous scientific analysis the teacher uses to evaluate the accurateness of evolution. The students will learn that the scientific evidence for the-heavens-and-the-earth-and-all-life-was-formed-in-six days theory of the origins of life is virtually nonexistent.

Moreover, substantial empirical evidence exists to demonstrate that the Bible has the order of the origination of life wrong. On day three, for example, the Bible tells us (Genesis 1:6-10) that God created "vegetation, plants yielding seed and fruit trees...." On the fifth day He made "birds fly above the earth" and "the waters teem with swarms of living creatures." On the sixth day He created the "beasts of the earth."

But geology teaches us that fish were in the seas hundreds of millions of years before a tree was on the ground. Birds did not appear until well after beasts of the field. And if a dinosaur is a beast of the field, then flowering and fruit-bearing plants did not appear until after beasts of the field.

If a Christian God as described in the Bible was not the agent of the origin of life, who, or what, was the intelligent designer? Here the diligent science teacher should offer a series of alternatives. One of the most compelling should command the attention of teenagers almost as much as sex: space aliens.

In his 1983 book The Intelligent Universe, respected physicist Fred Hoyle asks whether life could have evolved at random. "Impossible," he answers. That conclusion should hearten the intelligent design folks. But Hoyle does not dismiss the theory of evolution. His criticism of Darwinism is that it is an earthbound theory. Life derived from outer space. "Genes from outside the earth are needed to drive the evolutionary process," Hoyle concludes.

An even more intriguing and far better documented theory about the origins of life than Hoyle's is that of Swiss writer Erich von Daniken. Daniken's book, Chariots of the Gods, was translated into 28 languages, and has sold over 60 million copies worldwide. It was the basis of the much-watched 1970s television show "In Search of Ancient Astronauts."

Von Daniken amassed an enormous amount of evidence to substantiate his thesis, which he summed up this way: "Dim, as yet indefinable ages ago, an unknown spaceship discovered our planet. The crew of the spaceship soon found that the Earth had all the prerequisites for intelligent life to develop.... The spacemen artificially fertilized some female members of this species...." Over millennia they returned several times to repeat this procedure, each time breeding a more advanced human.

In some respects, Von Daniken bridges the theory of evolution and intelligent design. He agrees with the theory of evolution, but proposes that the evolutionary seed or seeds, were planted by space travelers. He notes that ancient civilization greatly respected such visitors and called them "gods." He records legend upon legend from one civilization to another whose records tell of the gods interbreeding with humans.

The creative biology teacher could build another bridge between Von Daniken and creationism. One Christian website for example, citing the sixth chapter of Genesis as its source, declares, "Von Daniken is correct... beings did, in fact arrive on at least two different occasions; and their visitation truly did significantly influence the course of human history, and they did interbreed with humans." But the writer continues, "These beings, however, were angels, not 'aliens from outer space.'" These are fallen angels, of course.

There's no question that if science teachers had their druthers, they wouldn't be teaching intelligent design or gratuitously criticizing evolution in their classrooms. But they do. They can whine or refuse or resign. How much better for them to take this opportunity to teach their students while exasperating their school boards with the power of thoughtful investigation. And have a whole lot of fun doing so.

"The religious right – backed by the President and rightwing members of Congress – believe that using a zygote to create and then harvest fetal stem cells is tantamount to murder."

(I am purposely using the medical term “zygote” rather than “fertilized human egg” or “embryo,” not because I fear use of those terms would undercut my argument but because it is more appropriate.)

The kind of research being done now in South Korea does not use fertilized human eggs. Instead they use an egg that has had its original DNA removed and replaced with DNA harvested from a different person
. That’s right, Dr. Dobson, no sperm was involved. Therefore calling the South Korean-creations “fertilized eggs” or even “embryos” is not entirely accurate. But they are, unarguably, zygotes....

...Anyway, the President and his fundamentalist supporters say that using zygotes to harvest potentially life-saving fetal stem cells is wrong.

...Things get even more confusing when you try to balance this anti-fetal stem cell position with the religious right's silence on fertility clinics. These self-proclaimed "prolifers" are also self-proclaimed “pro-family” folks who apparently have absolutely no problem with fertility clinics. This very strange since the stock-in-trade of fertility clinics is to create zygotes that really ARE fertilized human eggs, embryos. No doubt about it. Those little buggers are the real deal. And these clinics create them by the millions, because the failure rate of in vitro fertilization is so high they create many times more embryos than they will ever need.

So, what do these for-profit IVF clinics they do with embryos they don’t use? Well, first they thrust these "little“people” into vats of liquid nitrogen and freeze the holy bajeebers out of them. They leave them there shivering in this frozen hell, wearing nothing by their genes, until someone decides they don’t need them any longer. Then they thaw them out, and “take them for a ride,” – a one-way ride.

“The approaches of the 175 clinics that did dispose of extra embryos varied in the extreme. Some handed the tiny ball of cells over to the couple or individual to take home, whereas some incinerated them as biological waste. Of the clinics that incinerated the embryos, four required the presence of the couple while twenty-five clinics forbade it. Seven clinics even said a prayer during disposal in a quasi-funeral, according to Arthur Caplan, a co-author of the study from the Center for Bioethics at the University of Pennsylvania in Philadelphia.” (More)

"...So, let’s review. Using fetal stem cell research from artificially created zygotes is a sin -- abortion by any other name. But destroying honest-to-god embryos for profit by fertility clinics is not an issue with the religious right.

The reason IVF is not a political issue is, of course, money. Fertility clinics are insanely profitable. Fetal stem cells may or may not become a profitable business some day, but right now no real fetal stem cell business lobby is writing check on The Hill. Fertility clinics and the companies that own them are. And we are talking big money.

"On average, a patient gets pregnant only one out of three times, so many patients try IVF repeatedly. Each attempt costs anywhere from $4,000 to $18,000 for doctors' fees, plus thousands more for drugs to stimulate the woman's ovaries to produce eggs. Because patients are willing to invest that kind of money in treatments that didn't exist a few years ago - and because about ten percent of American couples have trouble conceiving - infertility is an estimated $2 billion industry annually in the United States. Pharmaceutical companies are investing millions in fertility-related drugs. Clinic management corporations traded on Wall Street are in the business of making a profit on infertility treatment for investors. Brokers are charging fees to help couples find egg donors and surrogate mothers. And the number of U.S. clinics offering IVF has been racing upward since the mid-1980s, to about 330 today." (More)

Ah, so there you have it. The real reason fertility clinics that really DO “kill” embryos by the millions are okay, but that it’s wrong to use artificially created zygotes for fetal stem cell research...."
