A leading Japanese research institute has opened an investigation into a groundbreaking stem-cell study after concerns were raised about its credibility.
The RIKEN centre in Kobe announced on Friday that it is looking into alleged irregularities in the work of biologist Haruko Obokata, who works at the institution. She shot to fame last month as the lead author on two papers1, 2 published in Nature that demonstrated a simple way to reprogram mature mice cells into an embryonic state by simply applying stress, such as exposure to acid or physical pressure on cell membranes. The RIKEN investigation follows allegations on blog sites about the use of duplicated images in Obokata’s papers, and numerous failed attempts to replicate her results.
Cells in an embryonic state can turn into the various types of cells that make up the body, and are therefore an ideal source of patient-specific cells. They can be used to study the development of disease or the effectiveness of drugs and could also be transplanted to regenerate failing organs. A consistent and straightforward path to reprogramming...
