A Japanese government-funded science institute said it has opened an investigation in response to questions raised about images in a groundbreaking study on stem cells.

The Riken research institute said Monday that it began the investigation Thursday, following allegations of irregularities in images used in two papers published last month in the British journal Nature.

The research, carried out by an international team led by Haruko Obokata of the Riken Center for Developmental Biology, found that mouse stem cells could be created by putting blood cells in a mild acid solution. If confirmed and extended to human cells, the technique could offer a safer and more ethical way to create stem cells and potentially help doctors use patient-specific stem cells in treating diseases. The Nature publication gathered global attention.

Riken said the images in question include a photo of a placenta that the authors said was created from the new kind of stem cells, which they called STAP cells, for stimulus-triggered acquisition of pluripotency. On Internet forums such as PubPeer, a post-publication peer-review platform for scientists, some commenters said the same placenta image seemed to be used multiple times. \* _1 L' q1 P- x

Riken declined to offer more specifics regarding the assertions and said it started the investigation after an outside expert brought the matter to the institute's attention.

Stem cells are unspecified cells that can produce any of the specific cells in the body. Scientists hope that research on stem cells could lead to work on organ regeneration and treatments for conditions including blindness and diabetes. |
