Riken is the Research Institute where the work was done. From a Japan Times article:
"“We believe the basis of the paper won’t be affected at this point,” Riken said in response to the move by University of Yamanashi professor Teruhiko Wakayama. “But we will continue our investigation.”

I've been sick for the past few days and hadn't seen the latest. I know there are instances of brazen deception but the scope of involved researchers seems to me to work against that possibility. I can't help but wonder if creating a window for challenging the patent isn't somehow a part of the controversy. There is potentially a huge amount of money at stake.

Riken discloses method for creating STAP cells after doubts raised
March 06, 2014
One of Japan’s top research bodies released online detailed steps of its revolutionary method to create artificial stem cells after scientists around the world said they are unable to replicate the trailblazing work.
A recent article in Nature magazine highlights research scientist Haruko Obokata and her colleagues' discovery of STAP cells.
Harvard scientist admits 'minor errors' in STAP cell report
February 22, 2014
WASHINGTON--A scientist who co-authored highly acclaimed research papers on a new type of pluripotent stem cell developed by a Japanese researcher admitted to "minor errors" in images, but said the findings were not compromised.

Co-authors admit 'mistakes' in images published by STAP cell scientist
February 19, 2014
A highly acclaimed study by Haruko Obokata, a rising star in Japanese scientific circles, who said she discovered a new and simple method to engineer pluripotent stem cells, is facing allegations that some of the images documenting her finding show irregularities.
Yamanaka labels concerns over iPS cells as 'misconception'
February 11, 2014
KYOTO--Nobel Prize laureate Shinya Yamanaka said the safety of induced pluripotent stem (iPS) cells has improved greatly in recent years, and reports that iPS cells can easily turn cancerous compared to recently discovered STAP stem cells are a misconception.
Scientists create iPS cells 20 times more efficiently than predecessors
February 07, 2014
Scientists have discovered a new method to generate induced pluripotent stem (iPS) cells that is 20 times more efficient than conventional methods.

Government laboratory mulls retracting groundbreaking stem cell paper

Wakayama said he used STAP cells received from Obokata in chimaeric mouse generation but was not involved in creating the cells.
He said he called for a retraction to other co-authors after learning that the STAP cell paper may have used images from a doctoral thesis of Obokata.
Wakayama said he will ask a third party to provide a detailed analysis of the STAP cells.
The paper was published in two installments by a total of 14 people in the British scientific journal Nature in late January.
Charles Vacanti of Harvard Medical School is among the 14. David Cameron, director of science communication at the school, said: “We are fully committed to upholding the highest standards of ethics. . . .
