Japanese stem cell scientist calls for retraction of study
The findings, published by Japanese researcher Haruko Obokata and US-based scientists, outlined a simple and low-tech approach in the quest to grow transplant tissue in the lab.
The study was touted as the third great advance in stem cells -- a futuristic field that aims to reverse Alzheimer's, cancer and other crippling or lethal diseases.But it faced hard questions as the Japan-based Riken institute, which sponsored the study, launched a probe last month over the credibility of data used in the explosive findings.
At issue are allegations that researchers used erroneous image data for an article published in the January edition of British journal Nature.
Teruhiko Wakayama, a Yamanashi University professor who co-authored the article, called for a retraction.
"It's hard to believe the findings anymore after so many mistakes in the data," he told broadcaster Nippon Television late Monday.
On Tuesday, the institute said it was mulling whether to pull back the study.
"We are considering whether to retract the report based on its credibility and research ethics, even though our investigation is still underway," it said.
In an e-mailed statement, the journal said: "Issues relating to this paper have been brought to Nature's attention and we are conducting an ongoing investigation. We have no further comment at this stage."
But Hitoshi Niwa, who also contributed to the article, dismissed what he described as minor mistakes, Japanese media reported.
Another co-author, Charles Vacanti, a tissue engineer at Harvard Medical School and Brigham and Women's Hospital in Boston, told the Wall Street Journal: "It would be very sad to have such an important paper retracted as a result of peer pressure, when indeed the data and conclusions are honest and valid."
Harvard is also investigating, reports said.
Hakubun Shimomura, the Japanese minister in charge of science and education, said on Tuesday that the study should be retracted now and re-published it if "they accumulate new facts" that prove its authenticity.
Called stimulus-triggered acquisition of pluripotency (STAP) cells, the innovation was touted as breaking new ground, supplying a lower-cost and relatively straightforward technique.
Stem cells are primitive cells that, as they grow, become differentiated into the various specialised cells that make up the different organs -- the brain, the heart, kidney and so on.
The goal is to create stem cells in the lab and nudge them to grow into these differentiated cells, thus replenishing organs damaged by disease or accident.
The researchers' groundbreaking findings said that white blood cells in newborn mice were returned to a versatile state through a relatively simple process that involved incubating them in a highly acidic solution for 25 minutes, followed by a five-minute spin in a centrifuge and week-long immersion in a growth culture.
Until now, only plant cells, and not mammal cells, have been found to reprogramme back to a youthful state through simple environmental factors.
A key obstacle in the field is ensuring that transplanted cells are not attacked as alien by the body's immune system -- meaning they would have to carry a patient's own genetic code to identify them as friendly.
In 1998, came the first gain: the use of cloning technology -- pioneered with Dolly the sheep -- to harvest stem cells from early-stage embryos grown from the donor's own DNA.
But these "pluripotent" stem cells are controversial as the method entails destroying the embryo, something opposed by religious conservatives and others.
In 2006, a team led by Shinya Yamanaka of Kyoto University, who was a co-recipient of the 2012 Nobel Prize for Medicine, created so-called induced pluripotent stem cells (iPS).
The team took mature cells and coded them with four genes, "rewinding" the cells' genetic programmes to return them to a juvenile state.
The technique had to overcome an early hurdle of causing tumours in cells and still faces efficiency problems -- less than one percent of adult cells are typically reprogrammed successfully.

Asian states search for missing jet
Planes and ships from south-east Asian states have joined forces to search the South China Sea for a Malaysia Airlines jet, missing with 239 people on board.
Flight MH370 vanished at 18:40 GMT Friday (02:40 local time Saturday) after leaving Kuala Lumpur for Beijing, where it was expected at 22:30 GMT.
The aerial search has been halted for the night but sea operations continue.
No wreckage has been reported by the airline, but Vietnamese planes reported seeing oil slicks in the sea.
The Vietnamese government said two slicks, about 15km (9 miles) long, were consistent with those that could be left by an airliner and had been detected off the coast of southern Vietnam.
However, there is no confirmation the slicks relate to the missing plane.
Separately, it has been reported that two passengers who were listed on the plane's manifest - an Italian and an Austrian - were not actually on the flight but had had their passports stolen in the past two years in Thailand.
US help
Distraught relatives and loved ones of those aboard are being given assistance at the airports.
"We are doing everything in our power to locate the plane," Malaysian Transport Minister Hishammuddin Hussein told reporters in Kuala Lumpur.
Malaysia Airlines chief executive Ahmad Jauhari Yahya said the focus was on helping the families of those missing. He said that 80% of the families had been contacted.
The plane reportedly went off the radar south of Vietnam.
Its last known location was off the Ca Mau peninsula although the exact position was not clear.
The Boeing B777-200 aircraft was carrying 227 passengers, including two children, and 12 crew members.
Malaysia's military said a second wave of helicopters and ships had been despatched after an initial search revealed nothing. The US has agreed to help with its aircraft too, Malaysian Prime Minister Najb Razak said.
Territorial disputes over the South China Sea were set aside temporarily as China dispatched two maritime rescue ships and the Philippines deployed three air force planes and three navy patrol ships.
Singapore is also involved, while Vietnam sent aircraft and ships and asked fishermen in the area to report any suspected sign of the missing plane.
"In times of emergencies like this, we have to show unity of efforts that transcends boundaries and issues," said Lt Gen Roy Deveraturda, commander of the Philippine military's Western Command.
The passengers were of 14 different nationalities, Mr Jauhari said.
Among them were 153 Chinese nationals, 38 Malaysians, seven people from Indonesia and six from Australia.
The pilot was Capt Zaharie Ahmad Shah, 53, who joined Malaysia Airlines in 1981, Mr Yahya said.
Friends and relatives expecting to meet passengers from the flight in Beijing were instructed to go to a nearby hotel where officials were meant to be on hand to provide support.
"They should have told us something before now," a visibly distressed man in his thirties told AFP news agency at the hotel.
"They are useless," another young man said of the airline. "I don't know why they haven't released any information."
In Kuala Lumpur, Hamid Ramlan, a 56-year-old police officer, said his daughter and son-in-law had been on the flight for an intended holiday in Beijing.
"My wife is crying," he said. "Everyone is sad. My house has become a place of mourning. This is Allah's will. We have to accept it."
The plane had been flying at an altitude of 35,000ft (10,700m) and the pilots had not reported any problems with the aircraft, Fuad Sharuji, Malaysia Airlines' vice-president of operations control, told CNN.
Malaysia's national carrier is one of Asia's largest, flying nearly 37,000 passengers daily to some 80 destinations worldwide.
The route between Kuala Lumpur and Beijing has become more and more popular as Malaysia and China increase trade, says the BBC's Jennifer Pak in Kuala Lumpur.
The Boeing 777 had not had a fatal crash in its 20-year history until an Asiana plane came down at San Francisco airport in July of last year.
Three teenage girls from China died in that incident.
Boeing said in a statement posted on Twitter: "We're closely monitoring reports on Malaysia flight MH370. Our thoughts are with everyone on board."
