Scientists create stem cells from adult skin cells

A breakthrough in human stem cell research could lead to the treatment of countless diseases, invaluable scientific research and yes, human cloning.

According to a study in the journal Cell Stem Cell, scientists have synthesized human embryonic stem cells from the cells of adults, creating two different lines from the skin of two donors.

Using the nuclear transfer method, scientists took DNA out of egg cells and replaced it with the donor DNA. The cells were basically reprogrammed, but of the 77 samples only two fully developed into cloned stem cells.

Lead researcher Robert Lanza says the 5 percent success rate isn't surprising. "Reprogramming is more difficult for adult cells than for fetal [and] infant cells, presumably at least in part because their epigenetic landscape from the pluripotent state," meaning the cells generally dont' have the right enzymes for change anymore.

The researchers reportedly tweaked a method made famous by the cloning of the sheep Dolly in 1996 and improved by scientists at Oregon Health & Science University just last year.

The nuclear transfer method is the third discovered way to harvest or create stem cells. In the past, scientists have extracted cells from leftover embryos after in vitro fertilizations, a controversial practice. And in 2006 a Japanese researcher discovered a way to create them by injecting new genes. (Via Asian Scientist)

Lanza's method could provide easy access to stem cells, opening up new research into diseases like diabetes, Parkinson’s and even leukemia. And according to NPR, the researcher wants to create a virtual library of cells using carefully selected DNA donors.

The implications of a real and viable approach for creating stem cells could be startling, and scientists have been wrestling with the ethical questions since the cloning of Dolly.

An official at Oregon Health & Science University thinks studying stem cells is necessary, telling Time,“They have become kind of like cursed cells. But we clearly need to understand more about them.”

But with stem cell research also comes the debate about human cloning. The director of the Center for Genetics and Society tells The Oregonian the practice should be preemptively outlawed. "If we're going to be having cloned embryos in laboratories around the country, we really need to get our act together and have a law that prohibits human reproductive cloning."

But how close are we to a world of body doubles and evil clones? According to Paul Knoepfler at theUniversity of California, Davis, not very. "I don't think that's coming anytime soon, but certainly this kind of technology could be abused by some kind of rogue scientist." ​(Via Universal Pictures)

It's still a toss-up whether this new method will prove better than other ways of creating stem cells from adults, but Lanza said it provides a new tool, calling it "another way to skin the cat."

  • Just in time for Thanksgiving, more than 100 members of Oklahoma's National Guard arrived at the Broken Arrow Armed Services Reserve Center Wednesday night. KRMG's told the unit had been serving a six-month deployment in the Ukraine as part of a joint, multi-national training group. They also provided training support to Ukrainian forces. The soldiers were thrilled to see their friends and family. “I’ve been waiting for this feeling,” one soldier said.  “I’m proud of everything we did over there, but I’m happy to be home.” More soldiers from the unit are expected to return home over the next couple of weeks. Feel free to thank the soldiers in the comments.  
  • We have a beautiful day ahead of us for Thanksgiving. National Weather Service Meteorologist Bart Haake says we'll see plenty of sun on turkey day. “Skies will be mostly sunny today with highs in the middle 60s,” Haake said.   If you’re heading out shopping Thanksgiving night or just walking off the stuffing, Mother Nature won't be an issue.  NWS is reporting mostly clear skies and a low around 42 degrees.   We're going to see higher than normal temperatures in the Tulsa area for Black Friday. “The highs will be in the low to middle 70s,” Haake said.   That's around 12 degrees above normal for this time of year.
  • If the thought of spending hours in the kitchen on Thursday just doesn’t sound like a good use of your time, what with family all around and the prospect of Black Friday shopping beginning at 7 a.m. that day, there are a variety of restaurants that just may have the answer for you. Several chain restaurants and many local ones are open on Thanksgiving, with options ranging from dining in to carrying out to catering the whole affair. Important note: Not all restaurants listed below will be open on Thanksgiving or offer special deals. Some franchise restaurants of certain chains may be closed. It is important to call the restaurant closest to you to confirm the hours and deals. These restaurants are set to be open on Thanksgiving.
  • The city of Everett, Washington, ,” but the baristas are not backing down. The baristas are arguing that their skimpy costumes fall under freedom of expression.In recent court filings, the city claimed the coffee stands have a history of prostitution, sexual assault and exploitation. One of Everett's new laws requires the workers to wear a minimum of tank tops and shorts. It specifically applies to employees at 'quick service' restaurants, which also include fast food and food trucks. >> Read more trending news The other redefined the city's lewd conduct ordinance and created a new crime of facilitating lewd conduct. Both ordinances took effect in early September. But seven bikini baristas and the owner of a chain of the coffee stands called 'Hillbilly Hotties' sued the city to block the dress code in September, saying it's vague, unlawfully targets women, and denies them the ability to communicate through their attire.  KIRO-TV asked a constitutional law attorney about that argument.  “That is not a frivolous argument. One can see that this is conduct which may not be pure speech, but nevertheless is a conduct that does enjoy constitutional protections. The question is how much constitutional protection,” said constitutional law attorney Jeffrey Needle. The Everett City Council unanimously passed the ordinances in August but halted the ban while the case is in court.  A senior U.S. district court judge heard the arguments Tuesday in a federal Seattle court.
  • Decades after they were banned from the airwaves, Big Tobacco companies return to prime-time television this weekend — but not by choice. Under court order, the tobacco industry for the first time will be forced to advertise the deadly, addictive effects of smoking, more than 11 years after a judge ruled that the companies had misled the public about the dangers of cigarettes. But years of legal push back by the industry over every detail means the ads will be less hard-hitting than what was proposed. Tobacco control experts say the campaign — built around network TV and newspapers — will not reach people when they are young and most likely to start smoking. “Their legal strategy is always obstruct, delay, create confusion and buy more time,” said Ruth Malone, of the University of California, San Francisco, who has studied the industry for 20 years. “So by the time this was finally settled, newspapers have a much smaller readership, and nowadays, who watches network TV?” The new spots, which begin Sunday, lay out the toll of smoking in blunt text and voiceover statements: “More people die every year from smoking than from murder, AIDS, suicide, drugs, car crashes and alcohol, combined.” Companies will also acknowledge their role in making cigarettes addictive: “Cigarette companies intentionally designed cigarettes with enough nicotine to create and sustain addiction.”
