A disgraced Japanese researcher has failed to replicate results hailed as a potential breakthrough in stem-cell treatment and efforts to do so will be abandoned, officials at her research institute said on Friday.

The scandal involving the research, which detailed simple ways to reprogram mature cells back to an embryonic-like state, eventually led to the retraction of papers published in the influential journal Nature and tarnished the reputation of Japanese scientific research.

The so-called STAP cells had seemed to offer hope for replacing damaged cells or even growing new human organs for sick or injured people, and made research leader Haruko Obokata a national sensation after the news broke in January.

But the discovery began to unravel soon after when other researchers said they could not replicate the results. Investigations by Riken, the Japanese research institute where Obokata was based, found she had plagiarized and fabricated parts of the papers, which were withdrawn in July.

"We were unable to recreate the STAP phenomenon," said Svinicki Aizawa, head of Aiken's verification team.

"We had planned to continue replication efforts until March next year, but in the light of these results, we have decided to terminate the experiments."

But when asked if this decision meant that the STAP cells did not exist, Aizawa said that as a scientist, he could not give an answer.

"All I can say is that we couldn't replicate the original results," he added.
